Send in the troops.
If by send in the troops, you mean to the border, I agree.
We don't have to send them anywhere, the invaders are coming to our borders. It is well past time that Trump shut this thing down by totally closing our southern borders. Stop ALL entry and exit from or into Mexico. Since the invaders attacked/overwhelmed Mexican police, why has Mexico NOT taken a stand to stop the invaders. If these people think they can just walk into the U.S., they are badly mistaken. Short of bullets, there are numerous other options to force them to disperse.
