What role does the US play in the war between Israel and the Hamas?
The US is already sending in a carrier fleet to show support for Israel; but one can imagine a scenario where Israel and Iran get into a serious confrontation, resulting in direct action by the US on the side of Israel. The US is also already supplying munitions and intelligence to the Israelis, and we should expect to see more in this area over the coming weeks and months. Note that the US might have to take drastic actions itself as its war materials are being dramatically reduced because of arming the Ukrainians against Russia, and now, looking to arm heavily Israel. It is quite possible that the US could be pulled into this in a direct way but currently, it just does not have the war material to conduct massive military operations if called to do so. This is quite a dramatic situation for the US, and of course for Israel.
