The Freedom Party is campaigning using anti-immigrant slogans, such as "Asylum fraud means a flight home," and is exploiting anti-Israel and anti-Jewish sentiments to win votes.
First is good, second is a crime.
But I have read the whole jpost article and I honestly doubt, that Israel or the "Jews" have any serious influence in Austria. Some leftists Austrians may use sometimes the Holocaust for their own goals, but ask them what they think about the serious points of this time, like the Iran-threat, the Muzzie terror, or even about the USA and Israel. What you will hear will be not nice.
So the influence can be maximal "moral", because until now no boycott worked well and the trade volume between Israel and Austria is too small.
My personal oppinion is that "moral" power is nothing.
