Trump's plan to get Mexico to pay for wall
It may be a way of attacking the illegal immigration problem by taking away one of the incentives for coming to the US, but it is not clear to me that the Mexican government would buckle under the threat. The likely results would be increased influence of the cartels in money transfers.
In a two-page memo to The Post, the GOP front-runner threatened to cut off the flow of billions of dollars in money transfers, payments that immigrants in the United States send back to Mexico. This idea could decimate the Mexican economy and set up a showdown between the U.S. and a key diplomatic ally.
