One major theme in the ongoing US-Russia conflict over the past decade-plus (dating back to at least 2008) is a fight over who gets to sell oil and gas to Europe. With the destruction of the Nordstream pipelines, and with countries like Qatar refusing to alter long-term energy contracts to increase supplies to Europe, and with Iran still under the Trump-era sanctions (which Biden continued), that mostly leaves the US…
Their coercion extended to bombing pipelines, too, of course:
