It's possible yes, though I'd argue that in regards to the Jewish people in the modern age, they're hardly going to face expulsion now are they. And I sincerely doubt they're going to be causing unrest or trouble, not that they did before.
I should hope not! But there were plenty of times when Jewish people were welcome and found acceptance somewhere....for awhile. Its a human problem constant in history. Even the Tang Dynasty eventually started expelling foreigners and persecuting other religions. No matter how cosmopolitan, the ugly head of nationalism and orthodoxy will rear their heads somewhere.
At the very least, the modern world has definitely made some improvements. But we're still half barbaric savages at heart. True global unity will be a challenge indeed. But one I think can be done very soon. The world has a global economy, a global culture (I daresay, that almost any culture on Earth right now has more in common with each other than any culture two centuries ago), and a global forum/political leadership (kind of. Its nascent).
