Most likely USA will be destroyed. Most American nukes are in their 50s-60s. USA also has a doctrine to cut loses as can be seen in Vietnam and Afghanistan. A quick sucessions of tactical nukes on American carrier fleets and pre-emptive strikes on 30 of American top cities will render American surrender. Even if they decide to launch, their ballistic nukes are interceptable, their satelites are now trailed by many Russian and Chinese satelite killers. As for F35, let just dig in that Israel F35 has been shotdown in Syria and likely another one F35 accident in Pacific in the last 24mths. Russia alone has about 20K nukes and deliverables with near 100% accuracy while USA THAAD and Patriots have been widely known as duds (Saud had to change their policies to make peace with Yemen and Syria because of poor American weaponry). By the way, USA imports Russian uranium. Considering John Titor's timeline America nuked and fractured in his timeline plus some East Asian prophecies about the fall of USA, I do believe WW3 would be a short one. The whole text of original Titor are in Library of Congress. Read that version. It did mentioned about Bill Gates and segway. Poles are widely known as military weak. Their only good one was their winged Hussars in medieval time. Already closed to 20K of theirs in Ukrainian as "mercs and volunteers" slaughtered. I dont think they willing to go WW3. They are too close to Russia, just purely on logistics, not enough Americans soldiers and artillery shells able to sustain Russian assault backed by Chinese factories. It is better they go for MYOB strategy. Doing Ukrainian or 80s Saddam-USA friendly Iraq policies are fatal. With Russians and Chinese establishing their influence in Iraq, Iran, Afghanistan, Africa, and now Ukraine I just dont see how EU can do much. Already they have to content with x6 fuel price without Russia and Chinese now able to half thrir fuel cost thanks to Russians gas pipes....that is 12x advantage just on energy alone. If you look at IQ and labor cost, EU sre serious outnumbered. We not even counting massive industrial espionage to bring EU IPs into Russia and China.
