The last two weeks have answered a central question of the Russo-Ukraine War; can Ukraine undertake the offensives required to liberate their people & reoccupy their territory? They have answered this question emphatically with their Kharkiv offensive. 1/19
2/ During this offensive, I had the opportunity to visit #Ukraine and to speak with high level military and government officials. I took away three key observations from the visit.
3/ First, the Ukrainians are competent. This is a gross understatement. No military this century has had to fight across all the domains of war concurrently, and do so against a larger and better armed adversary. kyivindependent.com/national/with-…
4/ Their most important preparation for this war was not physical but intellectual. They re-trained their troops away from Soviet centralised command methods to adopt more decentralised C2. This has been a clear difference between the two belligerents.
5/ Beyond this, the Ukrainians have adopted what I have described elsewhere as a strategy of corrosion. They have attacked the Russians at their weak points constantly, destroyed their logistics, and slowly killed as many Russian battlefield leaders as possible.
6/ At the strategic level, their global influence campaign has set a new benchmark for effectiveness. This Ukrainian competence has resulted in a military institution that is now without peer in the art and science of 21st century warfare.
7/ Second, the Ukrainians are proud of their national effort - military, civil, diplomatic and informational - to defend their nation against the depredations of the murderous, yet bungling, Russian Army.
8/ It is not a pride that features flag waving and empty patriotic gestures. It is a quiet, humble pride that one finds in the alert posture of every soldier, and confident step of the officials and military officers with whom I met.
9/ Finally, the Ukrainians are confident. They know they can win this war. Zelensky stated that “we don’t believe there is compromise when it comes to Russia. There are only conditions, especially the departure of Russia from Ukraine.”
10/ Partially, this is a result of their achievements in the Battles of Kyiv, Kharkiv and elsewhere. The Ukrainians have seized the strategic initiative in this war, and are taking back huge swathes of their territory from the Russians.
11/But there is another more vital source of their confidence; the Ukrainians know exactly what they are fighting for. They fight for their people and their country. And they believe strongly that they are fighting for the larger idea that all democracies matter.
12/ Every single Ukrainian interlocutor I met with in Kyiv had but a single message; give us the right tools in the right quantity to get the job done. They know they can beat the Russians, but appreciate that this is predicated on continued western aid.
13/ The coming winter is an opportunity for the west to surge its support to Ukraine. President Zelensky noted in our talks, “we are not after countries compromising their own security, but we need more military assistance.”
14/ There was a consistent message in what is needed: air defence; tanks and armoured infantry fighting vehicles; long range fires; soldier equipment; UAVs; and, counter UAV systems.
15/ Some in the west talk of the limits of Ukraine to absorb additional military aid. But Ukrainians know themselves, and this war, better than any western official, and have mastered modern war to a degree not achieved in any western military. We should defer to their judgement.
16/ There is much more we can do to support them. I have proposed that my own country send more armoured vehicles and equipment, and that it better amplify Ukrainian messaging in the global information domain. smh.com.au/world/europe/i…
17/ The coming months are an opportunity for Australia and others to demonstrate true commitment to Ukraine and their victory over Russia. This is an even more compelling need if Russia does begin to mobilise. reuters.com/world/europe/r…
18/ The sacrifices of #Ukraine in the past 8 months have been to ensure that ‘government of the people, by the people, for the people shall not perish’ from their small patch of this earth. It’s why they fight. And why the west must support them more. End
America has just released its 2026 National Defense Strategy (NDS). Not seeing much press activity from the Dept of Defense/War on this. While I need time to ponder the deeper implications of the document, a few things stand out on first reading. 1/11 🧵
2/ First, the document is consistent with the 2025 National Security Strategy (NSS) released by the Trump Administration in November 2025. Key priorities in the NDS align with the NSS, as you would expect. However, while the NSS has priorities, the NDS has "Lines of Effort". whitehouse.gov/wp-content/upl…
3/ There are four Lines of Effort in the new NDS:
1. Defend the U.S. Homeland. 2. Deter China in the Indo-Pacific Through Strength, Not Confrontation. 3. Increase Burden-Sharing with U.S. Allies and Partners. 4. Supercharge the U.S. Defense Industrial Base.
"The Oreshnik is the sign of a Fearful, Worried Putin, Not a Leader Confident of Victory." My first 2026 update on war and great power competition. This week: the Oreshnik attack, peace talks progress, the ground war in #Ukraine, China's reaction to Venezuela and more. 1/5 🧵🇺🇦 (Image: @DefenceU)
2/ In events related to #Ukraine this week, the Oreshnik strike absorbed a lot of attention. But this was not an event that demonstrates Russia's strength. Indeed it showed the opposite. Also, peace talks in Paris took place as did a meeting of the Coalition of the Willing.
3/ In the Pacific, China continues to posture about American operations in Venezuela. While we might like to think that China will practice what it preaches with regards to its statement that “military means are not the solution to problems”, its accelerating use of military coercion and aggression against neighbours shows just how hollow and hypocritical the Xi regime is.
Also this week, Trump discussed Taiwan in his New York Times interview.
On 29 December, just as the summit between Zelenskyy and Trump was finishing at Mar-a-lago, the PLA Eastern Theatre Command announced that it had commenced exercise "Justice Mission 2025" in the #Taiwan Strait. I have just published an assessment of what China designed it to achieve, and how we can learn from it. 1/8 🧵🇹🇼
2/ Exercise Justice Mission 2025 has taken place at multiple locations around Taiwan. While the maps demonstrate the physical environment of the exercise, the more important exercise “location” is the minds of Taiwanese and foreign observers. But perhaps the most important exercise location is the mind of the U.S. president. (Map: @TaiwanMonitor)
3/ The exercise will have been designed by the Chinese with multiple objectives beyond the normal political coercion of Taiwan. These objectives include:
-rehearsing military activities for different Taiwan contingencies, including decapitation operations.
-continue developing the skills of the commanders, staff, units and overall command and control of the Eastern Theatre Command.
-assess the response of Taiwanese and American political and military systems.
-normalise large joint operations around Taiwan.
Putin can play Trump like a fiddle. But the bigger issue is that Putin has clearly decided that continuing the war in #Ukraine - while keeping Trump on side - is more advantageous to him (for now) than agreeing to any peace deal. This is a deliberate Russian provocation to get Ukraine-haters worked up and undermine the peace process. 1/6 🧵
2/ Putin has wasted no time in making his views on the current 20-point plan clear. He does not like it, but needs to keep Trump from placing more sanctions on Russia. If the current peace plan isn’t dead, it may be on life support. Will Trump hold Putin to account for this however?
3/ And today, Putin held a carefully scripted ‘military update’ with senior military commanders to further shape the minds of decision makers Washington DC, Beijing and elsewhere around Russia’s inevitable victory. The key theme - everything is going well, the enemy (Ukraine) is doing badly and we must continue fighting to ‘liberate the Donbas and Zaporizhzhia.
The much-anticipated summit between the leaders of #Ukraine and America, held at President Trump’s #Mar-a-Largo resort, has just concluded with a press conference. A quick update on outcomes. 1/15 🧵🇺🇦
2/ This is the latest meeting between Trump and Zelenskyy since Trump returned to the White House in early 2025. Some of the meetings did not go well, such as the now-infamous 28 February Oval Office meeting. Others just kicked the can down the road, such as the Alaska Summit.
3/ In the lead up to the meeting, Ukraine released details of a 20-point peace plan that would be discussed with the Trump administration, and then potential presented to the Russians. The draft plan covered multiple subjects, including security guarantees for Ukraine, Ukrainian membership of the EU, reconstruction and territory.
Also, Trump had a 2.5 hour phone conversation with Putin - a call that was as long as today's main meeting between Ukraine and the US.
I recently returned from another research visit to #Ukraine, my second for 2025. I have written a new white paper, published by the @CSIS, which explores 7 strategic insights based on knowledge gained on my recent visit & other research. 1/7 🧵🇺🇦
2/ The white paper covers a range of subjects related to how #Ukraine and #Russia are fighting this war. The seven insights not only illuminate the state of the war, and the degree of learning and #adaptation occurring, they provide lessons that western military institutions must analyse and heed.
3/ The seven subjects covered are:
1. Drone saturation and Russian drone innovation. 2. The new tactical battle triangle. 3. The ongoing and accelerating adaptation battle. 4. Long-range strike operations. 5. Ground-based air defence. 6. Russia's tactical and strategic advantages. 7. War strategy and trajectory.
