Now that tanks are getting arranged, Ukraine wants fourth generation jets. I assume they have to have pilots, because training those from scratch could take a while... Still, it's not like they can just hop in the new ones, and charge the enemy head first.
Today I had the feeling we are heading for war. It's like in WWII, when US was pushing the equipment to it's non-allies via land lease (and they were already bought up all the wealth of the UK, from the beginning of the war for raw material, equipment, and armament). It's just a matter of time when NATO enters. Or is it? There is still the barrier of the nuclear weaponry, neither side willing to take the step. I think Russia will be pushed hard towards the direction to use tactical nukes by US and EU.
