The U.S. increasing weapon supplies to Ukraine poses a test on the evolving trust between U.S. and Russia, since the U.S. does not know Putin's exact red lines, and there are concerns about the potential of the longer-range missile striking targets inside Russia itself. There is also a discussion on whether or not the West should have given all the big guns right from the start so Ukraine could have quashed the Russians quickly rather than experiencing a drag on the issue.
