I've been assuming for a while now that one of Putin's strategies in Syria is to increase the number of refugees flooding into Europe. This helps to raise tension and conflict in the EU countries and ultimately to break down cooperation across Europe, not only in economics, but in military strength and commitment along Russia's borders. Less unity means it's harder for Europeans to stand united against Russia.
The influx of refugees has done all of this and more. On World Refugee Day (today), we're only a few days away from the British vote on whether to stay in the EU or not. [UPDATE June 25, 2016: they voted to leave the EU.]
Forbes seems to think that the refugees themselves will eventually make Europe more anti-Russian than it is today. That may be, but in the meantime, European unity is being severely tested. And the lives of millions of refugees are being being uprooted.
As the son of refugees who survived Nazi Germany because they were able to get out, my heart is with all refugees.
