Only 13 billion or so is going to actual weapons systems for AFU. That may buy a bunch of Patriot missiles, among other things.
But it appears that Patriots are not infallible, and most of those would be deployed around the capital and areas where foreign advisors are.
“Only 13 billion”?
With Europe and others more than matching US aid, that 13 billion will be huge.
More than just more Patriot missiles I think you will see many more patriot systems, enough to risk putting more closer to the front. Look what some ancient s-200 systems have accomplished.
If this happens, along with western aircraft and weapons systems and ammunition, the three main advantages russia has had, long range missile and drone attacks, air launched glide bombs, and artillery fire will be gone.
Meat and equipment wave attacks will become even more costly with even less results if not reversals, cost on Russian economy will soar even more, demand for manpower will increase not only the cost, but civil unrest over the war.
Can Ukraine push back the Russians, that is not a given, but increase loses and potential territorial loses may spark an internal crisis for putin, and that has been the scenario I have always thought the most likely.
Putin “loves” history, that is a repeated part of Russian history
