These are useful information, thank you. This is sad but also very true : "Both political parties want the issue to use as a hammer against the other side. So neither are motivated to fix it"

I was reading the other day about the history of nuclear energy (note1fjej6704h4gn3l2dg45s9u8q796atc89gzthz59mqn6q3ukplu7q5qhvnt) and most of the nuclear physicist who advanced the innovation in the US fled from Holocaust (mostly immigrants). While they are professionals, I'm sure there must have been some cultural adjustment. And in old sitcoms with Shirley booth as Hazel, Scottish and Italians were brought in as domestic help, cooks and so forth. But none throughout time was as intense as the border issue US faces with Mexico. I'm guessing its also a major economic disparity and high demand for a good life. And perhaps one way to really get to the root is to help Mexico build its economy.

On Israel - Palestine, I don't think there will ever be a fix. Nobody will give up the holy land, and gov'ts worldwide will milk the religious wars. But I also don't think the other party ie Russia, China, India, Saudi want a global war.

Then again I was reading a book on Sierre Leone and the RUF spread in the 90s and it was intense, cruel and recruitment spread like wildfire among children. The Northern Africa's religious movement was highly anti-US in the 70's and 80's. Its very easy to use religion as a ground to attack governments so it is worrying. After all, Persia - Iran, Afghanistan, Pakistan have a few things in common - talibans and extremist.

I don't know which way this will go, but i think this is only a prelude to nastier times ahead
