It doesn’t matter if a few mex types, or a lot for that matter get killed in flakey circumstances, just as in 1918 what matters is thee is armed push back against invaders.
Large numbers of US military who are heavily armed and told their job is to guard the border and there will be no questions asked about what is done to accomplish that will end this invasion. That the USMC even has some staff bullshit agency called the G-6 is another problem to be dealt with.
Wow...so you're A-OK with the accidental killing of American citizens and even kids and teenagers, just for the cause?
Breaking eggs for omelets and all that, not to mention your just-revealed racism against "a few mex types," i.e. Hispanics?
You really are clueless and have no moral compass.
