More on Mexico tariffs

I won't claim to try to understand Trump but Mexico spent a year negotiating a free trade deal with Trump and they all shook hands on it.

Now Trump is tearing it up before it's even ratified.

I assume it's a bluff but it doesn't send a great message about negotiating in good faith to anyone else who might want a trade deal with the US.

From Trump's twitter:

90% of the Drugs coming into the United States come through Mexico & our Southern Border. 80,000 people died last year, 1,000,000 people ruined. This has gone on for many years & nothing has been done about it. We have a 100 Billion Dollar Trade Deficit with Mexico. It's time!
