It seems NATO needs to either go all out and give Ukraine as much weapons as possible in the hopes of attaining a Russian defeat before winter or let Russia do as it wants in Ukraine. The Germans in particular have been tepid in giving Ukraine weapons (judge by actual deliveries and not public promises) and I wonder how long before they either fully support a Russian defeat or abandon Ukraine.
