RE: German Nord Stream pipelines exploded. Who did it?

I know next to nothing about european geopolitics, but it seems like only the USA has something to gain from that. The USA is known for using wars as an opportunity to make a lot of money, and now that the pipeline is destroyed they are taking swift advantage to export liquid gas to Europe. Everything went suspiciously well for the USA in a time when they desperately need money. What a lucky country, ain't they?

Again, I am not saying they did it, I am just saying they were lucky and seems like that is going to benefit them at the expense of everyone else.
