The EU on its own can put up a good defensive campaign, but offense is another story. I'm sure they would put forth a good effort and the UK would
perform the best out of all of them, but the rest would fall short due to lack of training, experience, morale and offensive capabilty.
For a comparison:
1.4 million reserves
1.4 million active duty
120 million fit for service (remember this is an invasion, the EU force would have to face most of the population)
Main battle tanks: 9573 (over 2500 more tanks than the EU)
Infantry Fighting Vehicles/Armored Personnel Carriers: 26,563
Combat Aircraft: 3389 (Not including drones)
Strategic Bombers: 179
Aircraft Carriers (All Super Carriers): 11
Now if you got the Russians and the Chinese, namely added Russian armor, airpower and Chinese cannon fodder you could wear down US military
If the assault is not overwhelming and sustained, the US would launch a counter offensive and deploy/produce advanced weaponry, e.g. drones, railguns,
and directed energy weapons.
If the combined effort in the initial assault is not well organized, it could easily result in the Russian, Chinese, and Euro navies and air forces
being almost wiped out.
One other major issue is sustainment, the Russians and Chinese would be unable to sustain long term combat operations in North America and the EU
would struggle to, especially if Canada was occupied by US forces. They could find themselves in a situation where the US would play island hop across
the Atlantic in a counter offensive until they reached Brussels. Best chance then would be to bog US forces down in Britain and negotiate for a
Any invasion of the US would be a huge gamble, especially if US anti-ballistic missile systems are effective and the invading force lacks an effective
system. The US would nuke its way to an armistice.
