Yeah, probably that's why US doesn't allow Polish jets be sent to their Germany base for the needs of our army, yeah.
Listen, you are overestimating the role of the US in this story and you don't understand the historical context of Ukraine - Russia relationships.

We have a long history of confrontation with Moscovia first, then being occupied by Russian Empire, later by the USSR ( Soviet - Ukrainian war, Holodomor - the man-made famine in Soviet Ukraine in 1932-1933 years, which led to a horrific death of millions of Ukrainians and followed by that settlements of the eastern and southern regions of Ukraine,INCLUDING DONBASS REGION, by Russians) and after we finally got our independence, which itself leaves a lot of questions like why the fuck we left a communist to rule our country, but even after that Russia in a face of Putin tried to interfere and force us to become a member of so-called Customs Union.

They tried to make their proxy Yanukovich the president of Ukraine by shamelessly falsifying the results of the president elections - it led to an enormous resistance from Ukrainians and so-called Orange revolution back in 2004 (I was there with my parents) where defended our right for the democratic elections. It didn't come out good because Yushchenko, after he got poisoned during the revolution, turned out to be incapable of resisting to the force of Russia and he made Yanukovich a premier minister. After that Yanukovich became a president in the next elections. This is where the history of our demitalitarisation began, the army was plundered, compulsory conscription was canceled, extended the lease of the Black Sea Fleet base in Crimea for Russia for another 25 years, greenlight for the Russian propaganda on the East of Ukraine and on it's Southern parts including Crimea, like for example there was a political party of Aksionov, who is now a head of the occupied Crimea currently, that was agitating for an annexation of the Crimea Republic to Russian Federation BACK IN 2010, 4 years before the Maidan. But Yanukovich realized, that with such visible and unhidden pro-Russian position his cadence won't last all 5 years so he started acting like he's about to turn Ukraine to the "European way", saying there are no alternatives for the eurointegration of Ukraine in 2013, meanwhile "secretly" bargaining with Putin for a better "conditions" for him and his party in Ukraine as a par of the Customs Union. After that he refused to sign the association with EU in Vilnius which led to a student protests (I was there) in the end of autumn of 2013. It lasted for some days until the Berkut, at that time some kind of a Riot Police, has beaten students viciously including women which cause a huge wave of anger amongst the Ukrainians, and this is how Maidan, the revolution of 2014 began.

After that the wheel of Russian Propaganda started spinning like a crazy one, Eastern part of Ukraine was flooded with separatist agitations, stating that some Nazis are preparing trains of doom to come here and banish and punish everyone who speaks in Russian, even tho in fact there was a huge amount of Russian speaking Ukrainians in central part of Ukraine including Kyiv, Kharkiv, Kropywnytski etc. And amongst the protesters there were many of them, mind me to say no one gave a single shit about it? To the fact, I must admit, bigger part of my life I used to speak in Russian. Well, unfortunately for the Russian propaganda, even tho Eastern Ukraine never had those nationalistic moods amongst te citizens, it didn't fall under the pressure of these fakes because there were still a lot of native Ukrainians unlike in Crimea, where the major part were native Russians and the opposition for them were Crimean tatars. So in most of the cities of Eastern Ukraine, where the Russians and separatists tried to seize by force the administrative building, they've got a major resistance so the Russia needed to send the troops to help separatists forces.

The operation was led by the Russian army veteran and former Federal Security Service (FSB) officer Igor Girkin (a.k.a Strelkov) who played a key role in the Annexation of Crimea by the Russian Federation and also Transdnistria, another Russian proxy project, an unrecognised breakaway state located in Moldova. It's an open source, nothing BREAKING, you can find the information for yourself Girkin even has his own blog, where he complains about Russian forces incapacity.
As a result of this operation Ukraine got a "smoldering" war conflict, huge humanitarian crisis as many people, who did not agree with separatist, left their home and moved to the other parts of Ukraine, and many many deaths of civilians and soldiers for these long lasting 8 years with an apogee of a full scale escalation and genocide of Ukrainians.

Putin made it clearly, he doesn't see Ukraine as an independent country. We were GUARANTEED with a sovereignty regarding the Budapest memorandum. The memorandum prohibited the Russian Federation, the United Kingdom and the United States from threatening or using military force or economic coercion against Ukraine, Belarus, and Kazakhstan. As a result of other agreements and the memorandum, between 1993 and 1996, Belarus, Kazakhstan and Ukraine gave up their nuclear weapon.
Agreements doesn't mean shit for geopolitics, that was a huge mistake made by our "leader".

We never wanted to be a part of NATO and never needed until Putin started to tighten us into his swamp in a first place so please, don't act like you know everything because you know nothing. Go spread the knowledge of how much of creatine you can consume so it won't be converted to creatinine in your body, do not "explain" me why my people including children and women are dying under the shelling of Ukrainian cities by the Russian forces.
"NoT sAyIng WhAt PuTiN DoInG iS rIgHt, BUT..." Oh, really? I don't care that you do not support Ukraine etc. But miss me with your stupid excuse for the Russian genocide towards Ukrainians.

Yesterday they bombed children and maternity hospitals in Mariupol, go tell them about the Cuban Missile Crisis.
