Yes, our rulers are insane enough to launch a military attack against China over Taiwan. From Mike Whitney at unz.com:

Washington is positioning its assets at chokepoints across Central Asia to block critical rail corridors that link Beijing to Europe. It’s part of a US plan to isolate China from western markets following an outbreak of hostilities in Taiwan.
The destruction of Nordstream is the key to understanding how Washington plans to deal with China. The pipeline effectively erased the geographic borders between Russia and Germany creating a de facto free trade zone that spanned the continents and increased the prosperity of both trading partners. The arrangement anticipated a much larger commons area that would extend from “Lisbon to Vladivostok”, in fact, that was Vladimir Putin’s explicit goal. Washington saw this as a threat to its regional hegemony and set about to scuttle the partnership and the pipeline. As we pointed out in an earlier article:
In a world where Germany and Russia are friends and trading partners, there is no need for US military bases, no need for expensive US-made weapons and missile systems, and no need for NATO. There’s also no need to transact energy deals in US Dollars or to stockpile US Treasuries to balance accounts. Transactions between business partners can be conducted in their own currencies which is bound to precipitate a sharp decline in the value of the dollar and a dramatic shift in economic power. This is why the Biden administration decided to destroy Nordstream, because Nordstream was the main artery linking the two continents together into a mutually beneficial relationship that operated independent of the United States. Thus, Nordstream was a clear threat to the unipolar world and the “rules-based order”.
Bottom line: Nordstream had to be destroyed.
The question is: What does the Nordstream incident tell us about Washington’s plans for China?
