There is something interesting going on here. Countries bought weapons from other countries, and did not think much of the re-export licenses they may one day need. It was assumed there would be no problem getting a re-export license because everyone would be on the same page.
Poland ran into this problem when trying to re-export German manufactured weapons, but Germany has now agreed. Switzerland will probably never agree to allow Spain to re-export to Ukraine. America is allowing re-export of just about anything to Ukraine.
The upshot, everyone is going to think longer about where they buy their weapons from. What good is buying weapons from Switzerland if they are going to block the use of them. This is going to be a good thing for American companies.
Brazil anong with most of South and Central America is much more looking to China than they are to America for leadership....that is the interesting thing that is going on here.
