Trump cannot give Mexico an inch. It is time to play hardball.
First, the burden is now on Mexico to stop the flow of immigrants and drugs; they dragged their feet for years and the clock has run out on them. Its entirely up to them to prove to us that they are making a serious effort to help us.
Second, our other trading partners waiting for a deal are watching closely and will be incentivized not to make any concessions if we let Mexico get away with doing little or nothing. We have to push Mexico hard. Other negotiations depend on it.
Exactly right. AND, Mexico is the weakest of the players aligned against us, therefore the easiest to get to cave in.
Once Mexico has fallen, the rest will give up. If Mexico wins, we have no future.
