Two Front War? Three Fronts? What's Biden's Game In Taiwan, Iran, And Ukraine?

The Biden Administration is becoming even more bellicose toward Russia and China over "crises" in Taiwan and Ukraine. Meanwhile US-backed Israel is attacking Iranian nuclear facilities. During the Cold War the hawks always pushed for the ability to fight a two-front war. Can a US military already bogged down for 20 years fight a THREE front war? Will someone in Washington display some common sense?
