Have there ever been military training exercise like this held in the US?
Not in modern times that I’m aware of. There were very large field exercises pre and post World War II, when it was much cheaper to move and feed troops, but this is something different.
The military conducts exercises all the time but usually on federal land or military bases. This one is different. And considering the hatred that baraq has for the State of Texas and his outright disregard for the rule of law, this is very concerning. We shall see what happens. Maybe nothing, but be watchful. He is a muslim communist who hates this country and all it stands for and he has all the power of the presidency.
