Syria is attracting European recruits who want to fight for jihadi rebel groups there (from Stratfor):
In April of this year, EU Counterterrorism Coordinator Gilles de Kerchove estimated that some 500 European citizens were fighting in Syria, most of them from the United Kingdom, France and Ireland. A survey by the International Center for the Study of Radicalization at King's College London found that up to 600 Europeans from 14 countries, including Austria, Spain, Sweden, the United Kingdom and Germany, have participated in the Syrian conflict since it began in early 2011, representing roughly 7 to 11 percent of the total number of foreign fighters in Syria. The study showed that the largest contingent of foreign militants -- somewhere between 28 and 134 -- came from the United Kingdom. (The number of foreign fighters could be higher considering that many likely cycled through the fighting arena and returned home in a very short time.)
Though no one knows the exact number of foreigners fighting in jihadist militant groups, reports occasionally surface about foreigners killed in action in Syria, Somalia, Libya and Yemen, among other countries. In March, for example, a Swedish man known by the nom de guerre Abu Kamal As Swedee and a Danish man known as Abdul Malik al-Dinmarki, both members of the Jaish al-Muhajireen wal Ansar, were reportedly killed in suicide bombings in Syria.
Survivors can cause problems if they return back to their European home and decide they want to continue the jihad rather than retire and tell jihad stories.
If Europe is such a recruiting pool for the jihad, why can't we recruit Europeans for the war on terror?
We already have non-citizens in our military. So this isn't a problem. So shouldn't we pursue this a little harder by actively recruiting for our military abroad?
If we can't get full commitment to fight at our side by more nations, lets get their willing citizens to join us. We already are moving toward seeing our enemies and potential enemies as sub-national entities rather than relying on the the outlook of the old Westphalian system of nation-states as the basic unit of international relations. Why not see our allies and potential allies that way, too?
Since Americans purportedly flee abroad (though our Hollywood types annoyingly remain despite promises) to live in a country more in tune with their beliefs, couldn't we host foreigners who wish to fight for our common freedoms and civilization despite their home governments' disinclination to fight?
This would also be a nice counter to the UN worship that some "citizens of the world" are prone to. Let's welcome Citizens of the West to our shores--and our military. We are in an ideological struggle and it isn't just for the hearts and minds of the Moslem world as we struggle to keep the jihadis from having the Moslem world's support. We need to struggle for the hearts and minds of Westerners so we will defend our common Western heritage.
I asked that question over 7 years ago. I still ask that question.
UPDATE: Related thoughts on the defense of the West against the forces arrayed against us, including the foreign jihadis fighting for the Moslem Brotherhood in Egypt:
And there are plenty of “foreign fighters,” just as there were in Iraq, just as there are in Afghanistan: in the last 8 days, according to usually reliable sources in Cairo, 253 Uzbeks, 21 Yemenis, 40 Afghans and 11 Turkmens have been arrested, along with 126 Hamas operatives, who bring weapons and train pro-Brotherhood Egyptians.
And yes, the destruction of the mullah regime in Iran would harm a lot of those arrayed against us.
