Why is the U.S. threatening trade sanctions on Mexico? Victor Davis Hanson says

Victor Davis Hanson : President Trump has threatened all sorts of trade sanctions on Mexico , a 25% tariff.

He says there are four things Mexico knows it has been doing to us with impunity, especially under Joe Biden , that are not sustainable.

Hanson: Mexico has the second -largest trade surplus of any country; it's getting close to China itself.

Victor Davis Hanson : Having Mexican nationals shut down American freeways and wave the flag of the country under no circumstances is going to win back American public approval.

Hanson: If Mexican President Claudia Sheinbaum was wise, she would negotiate with Donald Trump , get that trade surplus from $175 billion down to $ 30 or $40 billion .
