Baltics in NATO is good enough defensive measure to thwart any adventures.
However, if Russia attacks the Baltics, NATO won't be able to save Baltics and will have to run an intense campaign to put costs high for Russia to retreat. Hence having an extra squadron of planes or tanks or extra 50K troops is not going to help the Baltics against Russia.
So quit asking for an aid from US to make a stronger military for Baltics. Practically speaking, Israel will probably be the last country from which US will pull its aid from.
It seems your main issue is not Baltics but something against Israel. It seems a personal agenda, cannot help you with that.
Luckily the US military command is not as simple minded as you. Russia easily taking the Baltics will likely cause the collapse of NATO as there's really no point to it if the articles are meaningless. Even if it survives somehow, it won't have much of a purpose. Military alliance that's not an alliance, in what world does that make sense?
Russia taking over the Baltics and probably Poland results in Soviet Union pt. 2. That's bad for the US. Much worse compared to anything happening in Israel.
I already understand that US will support Israel no matter what they do. Israel could drop a nuke on Syria just because they can and US would still be talking about a peace process, lol.
The main issue here is American lopsided foreign policy and the fact that in the financial support to Israel, the only real beneficiary is Israel. I commend them for being smart in taking advantage of US, it's really quite brilliant strategically.
Just be straightforward and honest about it, no need for all the ridiculous explanations why US support to Israel is beneficial to US.
