Wars with Russia and China would be no less insane if the West was assured of winning, which it most certainly is not. From Caitlin Johnstone at caitlinjohnstone.com:

No one is more dangerous than warmongers who believe they can win an unwinnable war.
Multiple empire managers have made separate public statements around the same time which, taken together, serve as a disturbing reminder of the dark things our rulers have planned for our future.
The US Navy chief has unveiled a plan to be ready for hot war with China by 2027 while the US deputy secretary of state calls China the “most significant challenge” the US has ever faced in its entire history, at the same time the EU’s defense chief says Europe must prepare to fight a hot war with Russia in the next few years.
In an article titled “EU’s Defense Chief Says Europe Must Be Ready To Fight Russia in 6–8 Years,” Antiwar’s Dave DeCamp writes the following:
Andrius Kubilius, a former Lithuanian prime minister and the EU’s first defense commissioner, has said Europe must be ready to fight Russia within 6–8 years.
“Defense ministers and NATO generals agree that Vladimir Putin could be ready for confrontation with NATO and the EU in 6–8 years,” Kubilius told Reuters.
“If we take these assessments seriously, then that is the time for us to properly prepare, and it is a short one. This means we have to take quick decisions, and ambitious decisions,” he added.
These comments come not long after we learned that NATO is developing multiple “land corridors” to rush troops to the frontline of a future hot war with Russia in eastern Europe, while amassing hundreds of thousands of troops in preparation for such a conflict.
