If only this was our options.
I think there is enough of a contrast to determine which fits each role best.
@Druvius I don't think Biden advocates mass murder. He has spoken out against Israel's overly aggressive tactics.
Sadly, the U.S. ties with Israel have given the U.W. leverage in the Middle East for more than 60 years, and that long held U.S. policy was established long before Biden ran for his first political office. I do think Israel isn't taking much care in their attacks. However, Israel also didn't start this latest war, either.
I think the best course for the U.S. would be to hasten our conversion to more green energy, specifically in terms of transportation, so that we are not so dependent on foreign oil, and our alliance with Israel to hold power in the Middle East, and continued access to oil, is not as needed.
I remember Jimmy Carter originally had a plan to ease us off of oil dependence after the first OPEC embargo, but Ronald Reagan trashed the plan and since then we have only increased in our dependence on foreign oil, and republicans have fought hard to keep us dependent on oil, and other fossil fuels, ever since. Now that the climate is changing due to our over use of fossil fuels, republicans are still fighting to try keep us fossil fuel dependent. Why? Because there is a lot of profit to be made in wars. Wars which are inevitable as fossil fuels run out, if your dependence continues.
@Druvius I am unaware of Israel having "concentration camps". I am aware that the Gaza strip was territory taken in a previous Israeli war, and that the losers of that war never really accepted the loss of either the war or the land area, and have tried to dispute the loss ever since. Before the latest war started, people moved pretty freely.
I am not an apologist. If what you say is true, then it contradicts pretty much every news report of the area I have ever seen over my lifetime.
