There are plenty of people lining up to do just that in Europe. Those countries should be doing this and allowing American pilots, former military pilots who want to, to volunteer would be helpful.You fund a plane.
I'll buy a sortie of fuel.
Pilots will line up to volunteer.
Ukraine and other local countries can easily win this. We don't even have to directly support Ukraine if that bothers people, although I think we should give them all the weapons they can shoot and support short of troops on the ground, we can support the countries providing weapons to Ukraine.
Look, it's best to give them stuff now to end this sooner rather than later.
None of this had to happen.
