Make the case that Mexico has defended their border and is not aiding in illegal crossing of our border.
Oh, really? So if Mexico chooses not to shoot the protesters its ok for us to invade their country and shoot them?
You really need to think these things out a bit more.
Yes, we are the US empire. But we just cant go into any country we feel like. I know we do it all the time now..but it doesnt make it right.
