What part of “any remotely meaningful way” don’t you understand? The US providing vaguely defined precision guided munitions as a sign of aid isn’t anything remotely like providing millions of shells, hundreds of armored vehicles and artillery systems, billions of dollars in order to float the Ukrainian economy while the entire country is under sustained Russian strategic attack, etc., etc., etc.
Iron Dome is an Israeli system, not an American one. You’ll find the US under “foreign users”, with total US purchases of Iron dome amounting to:
In January 2019 it was reported that the United States would purchase two Iron Dome batteries for 373 million dollars. The batteries were to be deployed to protect US armed forces in hostile areas of operation.[128] The order was for two command posts and radars, 12 launchers, and 480 missiles[129] and was finalized in August 2019.[130] Rafael announced the first battery’s delivery on 30 September 2020.[131] On 13 November 2020, Iron Dome was activated at Fort Bliss to test if it could be connected into the Army’s air and missile defense network, to serve as an interim capability to intercept cruise missiles.
Everything else you’d provided as ‘evidence’ is no more than vague fearmongering. Those ‘some analysts’ who are worried that Ukraine has dangerously depleted western munitions either don’t know what they are talking about or do but know they are lying and are parroting Russian state propaganda. I’d suggest looking at the In defense of Russia thread in the BBQ pit for a thorough dispelling of this talking point.
Turkey is providing Bayraktar drones to Ukraine. Using the past tense of ‘was’ in describing an absurd hypothetical where they decide to stop selling them to Ukraine because of, um, reasons is absurd fearmongering. A deal to produce them domestically in Ukraine has already been worked out:

Minister: Factory to produce Bayraktar drones under construction in Ukraine
The Turkish company Baykar has already started constructing a factory in Ukraine to produce Bayraktar drones, Minister for Strategic Industries Oleksandr Kamyshin said on July 10, as cited by Hromadske news outlet.
The US will no doubt provide some dollar value of humanitarian and military aid to Israel as a visible sign of support, but that’s all it will be, a sign of support, not a huge sum of tens or hundreds of billions of dollars over the course of years which is what Ukraine needs and is getting from the US and the rest of NATO in order to survive. The US could give Israeli exactly $0 in new aid, and it will not affect Israel’s ability to deal with the situation.
Oh, and it might come as a shock to you, but Israel produces its own 155mm shells.

Israel buys tens of thousands of 155mm shells as global demand jumps -...
The $60 million deal with Israel's Elbit Systems comes months after the US reportedly pulled 155mm shells from pre-positioned stocks in Israel.
