This exactly, ought to have been done in regards to Iraq and Afghanistan. Congress never authorized or declared war on either nation. There was no imformed public debate. These were and still are illegal and unlawful wars.
Obama continued them on into his first and second terms. This means he consented to illegaligity and unlawfulness. He further authorized the NDAA to continue. This act makes America a battlefeild. Hence we have the police and military preforming drills and simulations on our soil. The troops are quartered, and this goes against the Constitution.
Yes our soldiers do train on our soil otherwise. But they are restricted to doing so on soil set aside for it, bases, established military ground. They do not train in the open public, civilian ground. At least they didn’t before America became a battleground.
