Some believe American withdrawal would strengthen European unity but the opposite seems much more likely to me. Without American protection and political support, old conflicts would re-emerge and Europeans would have a much harder time working together Is it possible for the European Union to emerge as a more powerful actor in the event that President Trump destroys NATO? For Europeans to come together to take care of their of their own security after decades of American protection? Sure, it's possible.

One final thought on the Leopard-Abrams saga: The main argument I've heard against sending Leopards (on their own) has been that they could lead to escalation by empowering the Ukrainians to beat Russia too hard. Once you link Leopard to deliveries to Abrams deliveries, there are essentially two options: The Americans block and you don't end up sending Leopards. Or, and this is what seems to be happening, the Americans change course and both Leopards and Abrams are sent.

The strategic genius that is Vladimir Putin has not only succeeded in forcing Germany to end its dependence on Russian energy but he has somehow manoeuvred himself into a situation in which Russian troops are about to face German battle tanks. What a colossal failure. Social Democrats, as reluctant as they have been to change course, have gone from talking about the "impossibility of achieving peace in Europe without Russia" to delivering artillery to Ukraine so that Ukrainians can fight off the Russian invasion. That's big.

All I want for the week is for Chancellor Scholz to clearly state his position on tanks and explain it to voters. Do you want to deliver Leopards? Do you not want to deliver Leopards? Will you allow others to deliver Leopards? Will you block others from delivering Leopards? Why? As it is right now, the debate could not be less productive. Everything has been obfuscated to such an extent that people can't even agree on basic facts. Is there a formal request for export approval from Poland? Would Scholz block it? If so, why?
