MISTAKES (AT LEAST) IN TANDEM

I must be returning to my 'normal' self in the election's wake. I read Paul Krugman's post which ends on how blithely much of the developed world is repeating the economic mistakes of the 1930s. And then it occurred to me, not only economically are the 1930s mistakes being repeated: in Europe, hatred of the Jews is at a level unseen since the 1930s. True, such hatred is in decline in North America (throughout the hemisphere?) and Israel is, thankfully, building or re-building good relationships with both Oriental (including India) and sub-Saharan African nations. Still, how much do these relationships 'weigh' when compared with the Islamist propaganda machine churning out anti-Jewish lies on a scale that would turn Josef Goebbels green with envy plus the increase of such rancor in Europe, abetted in large part by 'Muslim' immigrants?
Back in the 1930s, when the Jews needed refuge, the whole world turned its collective back on them. This will never be forgotten in Israel and among Jews outside Israel, nor should it be! Now let me ask: if Israel were not there, where would there be refuge for fleeing Jews today? Indeed, would there be any refuge at all for them? Let none treat this question hastily; take your time over it. Treat it with respect and consideration--that is, differently than how the Jews of  the 1930s were treated! That said, how much respect and consideration do the greater part of today's immigrants (at least to Europe) show their host societies? Or are the silently assimilating majorities obscured by the minorities trumpeting intent to conquer? If so, I hope the majorities put the minorities in their place, which I've heard is starting to happen. As an American who knows his country's history better than most, I know that most immigrants assimilate and change their adopted countries to some extent in the process as well.
Considering on the one hand Europe's real and/or imagined problems with today's immigrants and their slamming their doors in the Jews' faces in the 1930s, they're showing a remarkable consistency in making the wrong choices then and now. Jews have almost never brought anything but real benefits and imagined problems to their host societies; can the same be said of today's European immigrant minorities? Unless I'm mistaken, weren't today's European governments were under the impression that they were 'paying forward' the debt they owed to murdered Jews by admitting other 'refugees'? Or were they simply pursuing their own perceived interests and using 'paying forward' as window-dressing? I'm inclined to believe the latter myself. To me it is plain that the grinding of the faces of the poor and middle class labelled 'austerity' and growth in anti-Jewish sentiment go hand in hand, whatever bloviations come from the politicians on either side of the aisle or the Pond. I do believe the decline of anti-Jewish feeling in North America is joined somehow with the unpopularity of austerity here, and vice versa in Europe. Notwithstanding that fact, I still ask: how welcome would 'stateless' Jews be here, even today? And because I'm profoundly doubtful of a welcoming answer is a big part of my gratitude for the state of Israel!
A repeat of the bankrupt economic policies of the 1930s and another one of anti-Jewish rancor, now using the excesses of an unjustly beleaguered Israel as a fig-leaf. When mistakes are repeated, they come not single spies, but either in battalions or at least in pairs. How often will humans need to have their lessons written in blood, preferably their own, before they get it right?
