They couldn't hold all of those countries if millions of people had rifles........European countries took guns away from their people before World War 2 so they were defenseless once the Germans invaded
Sure they could have.
Here's the ugly little secret of WWII. Every country the Germans invaded, they found SHITLOADS of people willing to collaborate with them. Heck, some countries they didn't even have to invade, like Sweden which stayed Neutral but STILL sent thousands of guys to fight for the Nazis.
Fact is, more people joined Vichy than the Free French.
Switzerland had only 435,000 armed civilians and they were considered to hard a target for the Germans.......if every country in Europe was as well armed German socialists couldn't have invaded and hoped to hold the territory.
Switzerland wasn't invaded because the SCUMWADS were willing to launder the loot the Germans were stealing form the Jews.. You see, this is where you get your history mixed up, buddy.
Tank beats gun.
