I know Latinos that are pro Israel. One of my best friends is of Mexican descent and he loves Israel, his family does too. I also know people from Colombia who are pro Israel and Colombia gets a lot of weapons from Israel. Panama still refuses to recognize Palestine but yet recognizes Israel. I know many people here in my area who are military who are hispanic from Cuba, Puerto Rico, Mexico and Central America who support Israel.
I went to Mexico a month ago and didn't have any problems, I still think illegal immigration is an issue though.
