Bernie understands that if you don't stop injustice you will perpetuate a conflict. This is why he denounces Trump's Middle east peace plan and says the The United States can bring unequaled leadership to resolving the Israeli-Palestinian conflict, but we must use that leadership to promote a just and durable agreement. Israel must end occupation and enable Palestinian self determination in an independent state.
If we are to reboot the policies of our country to make the country work for all of us, then we must demand the same from our allies, especially Israel. A progressive President must reverse the Trump administrations rightward lunch. A progressive President will have many tools at their disposal to ensure American weapons and tax payers' money will not violate Palestinian rights.
