Just to be clear—we must defend the Polish and Baltic borders but we are banned from defending the US border against illegal invaders?
The decision about defending the Southern border is one made by the Progs and their idiot puppet Biden. Article V is a treaty promise made by the POTUS and Senate in 1949 and never revoked. We have not had to respond to an Article V event but Denmark has. Danish troops served in A’stan from 2002 to June 2021. The Dutch, the Brits, the Frogs are the rest did so as well. And they weren’t directly threatened by the Talis. A nation with the largest nuclear weapon stockpile attacking its neighbors is far more of a threat to us.
