Now to still try and make it work US need to continue to escalate the conflict (first Javelin will be a game changer, MANPADS, then Switchblades, then much needed M777 howitzers, now even more desperately needed HIMARS, next will be ) and as you previously noted everything comes at a cost. Where does that leave Russia, either sit back and do nothing or since US is setting a precedent that selling long range missiles is now acceptable practice and doesn't make you a party to a conflict, Russia can starts selling latest anti-air and anti-ship missiles to Iran, how much do you think it'd take for them to close the straight of Hormuz?

Turkey, Italy and Greece are connected to the Atlantic ocean through the mediterranean sea.

Super-funny the comment of the Mediterranean being connected. I guess then Taiwan is connected as well both on the east and the west, north and south through different oceans so all fine.
Some legal opinions state that selling weapons to a party in conflict is a legitimate trade according to international law and does not make you a party in the conflict. It does not remove your "non-belligerent" status no matter the precise weaponry, quantity or use - much more questionable to call that "neutrality". To be honest, I think that the RF would not want the US to be officially a belligerent party.

In general, Ukraine is seen as a country unlawfully invaded and defending its territory from an aggression. Most legal opinions would claim that selling weapons to Ukraine is helping restore international legality rather than taking part in a conflict.
My personal view is that selling material that will be used to defend the Ukrainian territory is legal and does not remove "non-belligerent" claims, as long as it is not used to strike in Russian territory - again IMHO even that would also bee acceptable if targeting troops or means used for the invasion. That is why US and UK have been very reluctant to send their versions of MLRS (the HIMARS) which have nothing to do with the RF MLRS - much longer range, technologically advanced munitions.
So, for now, even M777 that are used within Ukraine are perfectly acceptable IMHO. The switchblades, Javelin, etc.. are pretty much defensive weapons just to provide infantry with a fighting chance against armoured groups.
On Iran closing Ormuz, I do not see how that could be a defensive act. Attacking or blockading ships would be an act of war and it would justify a strong response.
Looks like MQ-1C Gray Eagle (upgraded predator drone) is the next "game changer" for Ukraine that's totally winning. And US military hackers conducting offensive operations in support of Ukraine, says head of Cyber Command
I'm not sure what ramifications would belligerent status bring to this, but pretty sure we're at the stage where neither Russia nor US would care about legalities much.
Iran has some disputed Islands in the straight of Hormuz and can claim 20km if internal waters around them, they threaten to close it every few years. Strait is only like 25km at it's narrowest, and Iran has a lot of land exposure around it Plus conveniently a third of the world's liquefied natural gas and almost 25% of total global oil consumption passes through the strait. If Iran gets its hands on some hyper sonic missiles, that can easily take out an aircraft carrier, that might be enough to change it's math to perhaps partial blocking of US military. China getting few hyper sonic missiles (which can take out an airfield) would instantly nullify billions in fighter jets and patriot missiles sold to Taiwan. Seeing how Ukraine is the most corrupt country in Europe, and with it loosing around 20% of its land to Russia i'd guess thousands of javelins, NLAWs and MANPADS can easily find their way to battle grounds where US is involved. Bottom line there are a lot of painful points Russia can escalate at in retaliation, and of course run away escalations lead from cold wars to hot nuclear ones.
Russia indicated that Ukraine was a red line for it, and cornered they really have no better option but to escalate, EU clearly indicating that it doesn't care much for the conflict and just wants it to go away, so we're only left with US still pushing it. Regardless of what happens (short of nuke war) Russia knows that it'll be warm (with gas/oil) and fed (grain) this winter, such certainties don't exist for EU. Knowing that, i just don't see how any escalation can make Russia capitulate, admit a loss and return to long term ruined economy, political unrest, shortages in high tech sectors (and most likely full collapse). That's why I'm confused of US end goal with such semi (but not too far) escalations, surely the expectation can't be of Russia folding and willingly collapsing, guess that's why Kissinger said what he said.
