Proponents of #SpaceForce think big. They thing space is big. But for security, #space is notably small. I explain.

Earth's land surface is divided into national territories. They're big enough to hide & hoard stuff & they can be controlled & defended by local regimes. +

1-Çin ile ABD arasında yaşanan ekonomik hegemonya savaşı, 2018 yılının başlarından itibaren yeni ve daha etkili bir evreye girdi. 2000’lerden bu yana dünya hegemonyasında ekonomik üstünlüğü ele geçirmiş olan Çin, bu hegemonyasını pekiştirecek yeni adımlar attı.

2-Trump,  Mart ayının ilk günlerinde, “çok aptalca olan ticaret anlaşmaları ve politikaları nedeniyle”, ABD’nin yıllık 800 milyar$ bütçe açığı verdiğini ve buna bir son vereceğini söyledi. Ardından, çelik ithalatına %25, alüminyum ithalatına ise %10 ek gümrük vergisi getirdi..

2/ Scientists are "really kind". #BlackpoolPIER
3/ And polite. #BlackpoolPIER
