Did he get a call from Putin? Does Trump want a piece of the action?

He probably received a check from Raytheon and Lockheed, that want all the global Patriot production business for themselves.

Zelinsky is saying he needs 300 Patriots for this coming winter. That is impossible. The US already shot off most of it's inventory fighting it's war with Iran, with Iran still not acting the least bit dead. Ukraine could not start production for a year or two, after it has the license in hand, due to the time needed to set up the supply chain.

Iran war depleted US Patriot missile stockpiles, creating readiness challenges, experts say

Using publicly available information on missile expenditures, production rates and estimated U.S. inventories, the Washington-based think tank estimates the U.S. has expended about 65% of its Patriot inventory, leaving fewer than 1,000 interceptors remaining. The analysis also estimates U.S. inventories of Terminal High Altitude Area Defense, or THAAD, interceptors have declined by about 38%, leaving an estimated 234 to 278 interceptors.

So, Trump can throw our guys under the bus, to supply Ukraine, or throw Ukraine under the bus, to protect our guys...and Israel, of course. Trump is blaming the shortage on Biden giving so much to Ukraine, so seems Ukraine will be the most likely one sacreficed. Speculation is that Ukraine attacked an Iranian ship, in a desperate ploy to get itself delt in to the shrinking supply.
