"The US must react"

It has by accusing Russia of assorted nefarious motives while at the same time not making a single squeak about blatant Ukrainian thievery.   The US then expects Russia to supply it with LNG and complains that there isn't enough investment in Russian oil and gas production.   Why should Russia do anything for the USA?  The US walks and talks like Russia's enemy and at the end of the day it is Russia's enemy.

The US doesn't want Russian LNG as far as I know. Please cite?
