Proxy war is proxy war. NATO and Russia in actual war with each other, that's something different.
True - but people seem to have forgotten how direct the aid flowed in some of these wars.
During the Yom Kippur war both the U.S. and U.S.S.R. were delivering fighter jets to their respective proxies on a 1:1/Same-day basis. Jets were replaced literally as fast as they were shot down. Now people worry that giving Ukraine jets would mean war with Russia - based on Cold War history, that's not the case.
During the Korean war, North Korean jets had safe harbor in China - that's didn't widen into a U.S. invasion of China.
I think we could make an argument for giving jets to Ukraine and allowing them to operate from Polish or Romanian airfields, and have cause to not to expect Russia to attack those nations directly - that's based on how things happened during the proxy wars of the Cold War.
Two things I have noticed on this. One is that Turkey apparently delivered more drones to Ukraine yesterday. More than one, but the numbers are not clear. The delivery fit on one A-400 cargo plane, which is midway in size between a C-130 and an C-17.
The other thing is the drama with the old Warsaw Pact jets. There was talk of turning over Polish and Bulgarian jets -
as many as 70 of them. At one point
Ukrainian pilots were supposedly bussed to a Polish airfield to take possession of them. The idea was to give them the Soviet-designed jets because that's what the Ukrainian pilots knew how to fly and the ground crews to maintain, plus they already have the right tools and a supply of spare parts - no new training.
But the deal apparently fell apart, completely. It seems the whole concept of transferring older Warsaw Pact-inherited NATO jets is deader than dead and not expected to be revived.
There is, however talk of an American company that owns four Soviet jets used for training, that company has stated that it is willing to "transfer" them to Ukraine if approved to do so by the U.S. government. I don't know if was intended to be a donation or a sale, and I can't remember if it was Mig-29s or Su-27s. Can't find the link anymore.
I looked up info on the Turkish drones. Cruising speed a blinding 70 knots, with an operating altitude of 18,000 feet/5500m. Payload of 150 kg with four hardpoints. So if it is based on an airfield in western Ukraine, it might take eight or nine hours to get to Kharkiv or Mariupol, maybe one round trip a day. Use it's four missiles, than back west again. Then again, it has a loiter time of 24 hours.
