Here is my theory. Let's take the Russians, Germans, French,British, and Americans. From events in the past, we can see that all of them are capable of shaking the world, and wreaking enormous amounts of damage.
Look at Stalingrad, Dresden, Berlin, France, London, Coventry, Tokyo, Hiroshima, Nagasaki. Literally millions killed by riled up people. We know what capabilities we have, to ruin a lot of people's days.
The problem we, and Europeans have, is that the government is on the side of the slime bags causing all the problems. Obungler just visited a mosque. What does that tell you?
We know, if we did what the Russians did, we would all be individuals going up against the weight of the entire government. Imagine one guy, trying to take on the Army. It's a losing proposition. We would all be killed almost immediately, or put in the deepest darkest dungeon.
The Russians, on the other hand, from what I can see here, do not have the government harassing them like we do. The cops didn't mess with them, so these guys did what they had to do. The Russian government is not on the side of the bad guys.
To say we can't inflict unbelievably severe amounts of casualties, is untrue. We can, but the government is on their side, not ours.
We live in such a litigious society we are afraid of getting involved for fear of financial ruin, and the enemy knows that.
Go there for a visit. It's not cheap but it's well worth the trip. My husband and I went to St. Petersburg a few years ago. Their newspapers print ANYTHING but the "Pravda." Well, that was OUR read.
