Yes, that is true, and not just of Hungary. Much of what we consider nations in Europe were not so for that long and were badly formed in the aftermath of WWI and WWII.
On the other hand, Germany's numbers are not disputed, and she has almost 10 times the population.
Well, first there's the fact that you're always wrong.
But if it comes down to logic, yours is more than flawed. It is the equivalent of saying a parole board released a criminal, and he committed a murder three months later. The parole board did not cause the murder -- the murderer did.
That the US has been involved in destabilizing the region is indisputable, but there is also the passivity of much of Europe and East Europe. Until the crazies begin blowing up your press offices and train stations, many are content to let others stick their necks out in the hot spots. And the Crimean crisis has proven, a lot of Europe is more afraid of Russia and her gas pipelines than they are concerned for invading forces in a neighboring state -- a morality of convenience.
Neither the EU nor the UN get a free pass just because some other crises happen simultaneously.
The US absorbs millions of Latino immigrants each year, but I don't see any country in Europe stepping up to say "send some here -- we welcome all."
The de facto assumption that millions must flee Syria to Europe is unsupported anyway. Is Europe the closest place of refuge? Doubtful. It is more likely it is the most lucrative economically, not the nearest place of safety, else where did all the women and children go?
