There are many campaigns to boycott Israeli products and companies that support what the IDF does. Here is a link:

Starbucks
McD's
Home Depot
Another thing is ask your employer not to invest your retirement in certain stocks that are Israeli companies and divest any that you own.
Money talks, and governments listen.
