What happened when Denmark let in 321 Palestinians?

People say all this about how immigrants are criminals in Europe or whatever. And the thing is. Criminals should be punished but like. People don't seem to ever look into why there's so much immigration from the middleeast. People think this happened out of nowhere. It's almost like if you have constant wars and genocides in your region you would want to leave it for somewhere else. Yet somehow anti immigrant mfs never came to the conclusion that this is all Israel and america and uks fault and if the middleeast was left alone and allowed to grow rich and powerful then none of the mass immigration would of happened and no terriost organizations like isis would of been formed under the power vacuum after kicking out the strong legitimate Muslim governments like gaddafis libya. Imagine if Israel didn't exist and Palestine was this rich independent utopia. Then there would be zero immigrants in Denmark unless it's rich expats that respect the culture. Israel's existence is why this happen
