There’s almost no chance Ukraine wins anything by winter, which means the U.S. and NATO will quite writing the checks and sending the equipment. From John Helmer at johnhelmer.net:

For all its public talk, NATO has agreed on a secret six-month plan for Ukraine. It’s a case of do or die by December.
Either the Ukrainian forces, firing everything the NATO allies can give them — from US cluster munitions to Franco-English Storm Shadow missiles and German Leopard tanks — will gain territory and advantage over the Russians; or else the Kiev regime will be destroyed and must fall back on Lvov while NATO beats its own retreat westward from the Polish and Romanian borders — its military capabilities defeated but its Article Five intact.
This is hardly a secret. “Whatever is achieved by the end of this year will be the baseline for negotiation”, the Czech President Petr Pavel, former Czech and NATO army general, announced on the first day of the summit meetings in Vilnius. There is no more than a six-month window of opportunity, Pavel added, which will “more or less close by the end of this year”. After that, “we will see another decline of willingness to massively support Ukraine with more weapons.”
The difference between the Czech’s “more or less” was explained to Ukrainian President Vladimir Zelensky by Henry Kissinger on the telephone. But the telephone was rigged, and Kissinger was talking instead to the Stavka in Moscow, in the guise of the pranksters Vovan and Lexus.
Learn from the war machines that almost got there, reach Moscow before winter or give up on it.
Watching the videos at the excellent Greek 24-7 war page and the Uke tactics are not up to par.
