Yeah, and in the beginning of WW II, the invasion of northern France by German troops was not sanctioned by the Belgian government... So by your logic, the French would have been wrong to respond to those hundreds of thousands of German troops pouring over the French-Belgian border.

Apples and oranges....
Those German troops were armed when they invaded northern France....
Our border has a problem with controlling who gets/ comes in, not repelling a military force to conquer and subjugate us....
It’s definitely a problem, but not comparable to WWll
