You want to kill a lot of teenagers to get back to the exact same place we are at now. Real smart.
Kids in black hoodies throwing rocks and bottles are mere cannon fodder of the real enemy. It's going to take force to dislodge those who are actually in charge of slowly stealing that American territory.
And if they're allowed to secede, as you foolishly want them to, other states will follow. In short order, the whole Union will be broken, and the country will be too splintered and weakened to resist an all-out attack from foreign aggressors.
Is that what you want, or have you not stopped and thought through the logical ramifications of what you're proposing?
