>If people in the US try to turn climate action into a blame game, it will end very very poorly for the US.

Pure fantasy. What will happen to the US and who will do it to us?

The US can't even get countries to enter trade agreements anymore, because it's throwing around threats of large tariffs and annexation of others' lands. The world could drop the dollar as the reserve currency, something that was gradually happening but is now accelerating.

If the US starts trying to force other countries into climate action without taking into account its own contributions, the US will likely cut out of the global economy, and become far poorer as the rest of the world surpasses its wealth through vigorous trade.

The US was the sole remaining superpower, but has recently decided to only occupy a much weaker position with a mere "sphere of influence" and ceding leadership in other parts of the world to others. The US is signalling to allies in Europe that it will no longer lead, that the prior world is over and the US is bugging out, meaning Europe will gain far more influence.

The more that the US attacks others without providing any leadership, the less that the US will be able to take from the world. Up until recently, the US's position of massive economic strength was largely due to it's dominant position among nations and the goodwill that others had towards it. Turning the climate problem into a blame game on other countries would further weaken the US's position and options.
