The Biden administration on Monday sent Congress an urgent warning about the need to approve tens of billions of dollars in military and economic assistance to Ukraine, saying Kyiv’s war effort to defend itself from Russia’s invasion may grind to a halt without it.
In a letter to House and Senate leaders and also released publicly, Office of Management and Budget Director Shalanda Young warned the U.S. will run out of funding to send weapons and assistance to Ukraine by the end of the year, saying that would “kneecap” Ukraine on the battlefield.
She added that the U.S. already has run out of money that it has used to prop up Ukraine’s economy, and “if Ukraine’s economy collapses, they will not be able to keep fighting, full stop.”
Israel has been involved in several wars against multiple other nations - for example, in the 1973 Yom Kippur war, it was invaded by Egypt, Syria, and a coalition that included Saudi Arabia, Morocco, Cuba, Jordan, etc.
Israel is located at a fairly strategic location. Britain and France used Israel during the Suez crisis to stage an attack against Egypt over control of the Suez Canal. The Suez Canal is one of the most important global trade routes.
US support of Israel is a combination of funding American arms dealers and wanting Israel as a strategicly located partner. That’s why we fought proxy wars with the soviet union over it like the Yom Kippur war. The aid is intended not to fight Hamas, but to keep Israel strong against e.g. Iran and other neighbors. They’ve had peace with Egypt for decades, but that might be more because of Israel being strong enough to not be worth attacking.
I doubt Biden personally supports the Gaza war, but a lot of this stuff is more about realpolitik and strategic concerns than anything else.
