My advice? How about we cut off trade with Communist China and stop doing business with a country that still throws people in jail for being a Christian, threatens us with a military build up and which is the sole support for North Korea.
I do have some sympathy for him, but of course not on immigration. Mexico was one of the first countries to have a Marxist revolution and we were good buddies with the PRI dictatorship throughout its life (when it got reelected in election after election for 7 decades) and there were plenty of atrocities down there too.
I’d also like to see Bush (or any prominent Republican) point out the millions who died because of communism in Korea, China, Russia, Vietnam, Cambodia, Laos, Cuba etc, etc and why our efforts to stop them were not bad and we should not view them as mistakes. Compare the standard of living in North and South Korea and challenge the world to say intervention did not help -and how much better they could all be if we had been more aggressive. Then, just as an “FYI” point out that the Democrats have always moaned the loudest about fighting these murderous communists.
