Us -> Europe gas supply is LNG via boat. It can take up to a month to deliver something like that from the US to the shores of the UK/France/etc. Then distribution needs to occur.
Yes, the US can profit HUGELY off this but it seems stupid to hurt their ally considerably for the sake of stopping bargaining (which may avoid a world war). Given that the US can't supply immediate relief the profit over winter is severely limited and Europeans will suffer even with the shipments. I just can't see the US doing such a thing because it would certainly mean being driven out of NATO, and potentially Europe going to war with the US.
