All the libs will go back to brunch and sleepwalk for another 4 years. Harris will fail at everything she does and make life worse, especially for Muslims, and the left will be blamed for everything. The right will dig their heels in even more on reaction, yada yada, y'all know how this show goes.
The US and NATO can barely make enough ammunition to keep Ukraine and Israel afloat, and that's with still having full access to Chinese imports (chips, raw materials, etc.). They'd be hard pressed to last 20 months in a hot war against China and Russia, even 20 days would probably be pushing it.
That seems highly optimistic
In fact it sounds exactly like the way people were talking in 1914
