Russia know it better than most, being the target of countless invasions of varying degree of success, form and scale.
Let's see, there was Napoleon, the Crimean War invasion, WW1 Germany, WW2 Germany... I think I counted your countless invasions. Looks like four.
How about the countless invasions of other places by Russia? 1792 invasion of Poland, 1809 invasion of Sweden, 1808 invasion of Swedish Finland, 1809 invasion of Sweden, 1853 invasion of Moldavia and Wallachia, 1855 invasion of Ottoman Turkey, 1877 invasion of Ottoman Bulgaria, 1878 invasion of Ottoman Turkey, 1914 invasion of Germany, 1914 invasion of Galicia, 1919 invasion of Ukraine, 1920 invasion of Poland, 1939 invasion of Manchuria, 1939 invasion of Poland, 1939 invasion of Estonia, 1939 invasion of Latvia, 1939 invasion of Lithuania, 1939 invasion of Finland, 1944 invasion of Romania,1944 invasion of Albania, 1944 invasion of Yugoslavia, 1944 invasion of Bulgaria, 1945 invasion of Slovakia, 1945 invasion of Croatia, 1956 invasion of Hungary, 1968 invasion of Czechoslovakia, 1979 invasion of Afghanistan, 2008 invasion of Georgia, 2014 invasion of Crimea, and these are just the unilateral invasions, where Russia invaded by itself without any allies, and doesn't even count Russia's secret invasions if importing thugs and weapons to destabilize countries like it did in Armenia, Azerbaijan, Georgia, Belarus, Spain, China, Korea, Vietnam, Zimbabwe, Cuba, Mozambique, Angola, Somalia, Egypt, Syria, Salvador, Nicaragua, Chile, Dominique, Nicaragua, and more recently Chechnya and Eastern Ukraine.
A bit more difficult to count that second list, huh? But that's typical Russian for you: take the bad thing that your country has done, and claim that it was actually done to your country by others.
You forget that many of those atrocities were committed by the USSR junta, Russia's evil oppressor. First, they defeated Russia. Then, with Russia under zombie-control, they defeated all of the other future member states. I'm not sure how the USSR managed to carry out such a sophisticated attack (I wanted to call it a coup d'etat, but apparently there was a lot of bloodshed). My theory is that the Russian people just didn't care -- they were paralysed by apathy, rendering them helpless.
Remember that Germany's GDP is only a couple of trillion
