@resist1984 Unfortunately the list of companies deeply embedded in Israel is very long. They include Google, Intel, Microsoft, AT&T, and a slew of others. You basically need to throw out your cell phone and computer which is not really an option for companies or individuals. Other strategies need to be employed.
@krock boycotting seems to be the easiest thing we can do as individuals, but else do you have in mind? Americans can vote against US politicians who support Israel's oppression & expanding colonization, but that's a bit of a futile effort in a 2 party system. All the power is on the side of oppression.
@resist1984 Pressure should be applied on all fronts, but I have no great recommendation. My point is that the US and a very large number of its tech and A&D companies are deeply invested there. These companies and the US gov could pressure Israel but are unlikely or unable to abandon Israel.
