Let Ukraine paramilitary units like Azov brigade go into NATO Eastern Europe as individuals and receive training and weapons and supplies they take back with them. This avoids the US going into Ukraine and training the Ukrainian army.
Instead we can use cover forces like private security companies to train Ukrainian paramilitaries in Eastern Europe. This way we can avoid provoking Russian nationalism and give Putin an out.
Supplies are sent in trucks with the paramilitaries as they go back. Ukraine can be given financial assistance instead of direct military aid. They can buy supplies on the open market.
It is the reality of Ukraine developing an army that matters. This is a matter of will and financing. It doesn’t have to be under a US flag.
