serbs shot down an american "stealth" fighter with a russian radar rocket system from the 60s...chineese can spot US "stealth" with a fishing radar...albeit a quantum fishing radar, but still, a fishing radar...a sweedish sub can sink a 6bn$ carrier...
I mean sure, the invaders bomb and cruise missile some 3rd world rubes and get illusions of grandeur about themselves...but IRL, all nukes aside, they do not stand even a theoretical chance against russia or china in a real conventional war...
china will own asia in a decade...no asian country will want to piss off the #1 economy in the world...look for an asian union in the near future...good luck to the euro zone skeptics
tiny pissant countries want to compete with the asian union
the only question is, will europe side with the #1 economy or the #4?...not a tough choice IRL...
