I don't understand the reasons for this massive admiration of Ukrainians for Western weapons, it looks like a cargo cult. The F16 fighters are an approximate analogue of the MiG-29 fighters, of which Ukraine had noticeably more than the wildest expectations for the supply of F16, and most of them have already been spent.
I don't know where you're getting these numbers from. First you claimed that between 100 or 200 F-16s would not change anything for Ukraine, now you say they had more of their own jets before the war...
Ukraine had around 100 fighter jets total before the war (of various types) which included less than 70 MiG-29, so getting even 100 F-16s would be a greater firepower than they ever had in store.
In April, Ignat said on the Kiev TV channel that Ukraine had three MiG-29 brigades (about 72 units), it seems that after that Poland transferred another 14 MiG-29s and Slovakia transferred another 13 MiG-29s, a total of about a hundred units to the beginning of summer. Their influence on the course of the operation, I assess as minimal, Ukraine launched a counteroffensive with little or no air support. What makes you think that if you double or triple this number, it will decisively turn the balance of power in the air in favor of Ukraine? For the F16, a longer runway is needed; it’s trite in Ukraine that they have nowhere to take off from. There are no spare parts or repair teams for F16 in Ukraine. There are no trained and experienced pilots for F16 in Ukraine. The longer you wait for F16 deliveries to Ukraine, the more disappointed it will be.
