Some interesting insights and statements in that article.
One is the implicit idea that ISIS is ultimately a military problem, to be solved by military action. I find that highly questionable.
Another is the IMO rather odd expectation that there is such a thing as a desirable "US Leadership" in the Middle East that is supposed to be growing "by default of other players". That is an exceedingly dangerous idea to consider.
This statement, in particular, I find almost funny, bordering on satyrical.
But most players still want to hold America’s coat while the United States does the bulk of the fighting.
I have no idea how sincere it is, and I guess I know little about how much fighting is happening there, let alone how much of it is made by US troops.
But I do know that after over ten years of largely pointless troop presence in Afghanistan and Iraq, the US public opinion will be very much opposed to any significant numbers of US military presence opposing ISIS on the ground. Paying mercenaries, sure. Cowardly loosing bombs over ISIS, no doubt. But "the bulk of the fighting"? This sounds like a misguided joke, really.
Then comes the best part of the article. Despite being brief and poor in detail, it still reminds us that the region is basically doomed to instability in the predictable future. An almost accidental description of the regimes of Mubarak in Egypt, of the Assads in Syria and of Gadaffi in Lybia as "secular" reminds us of how relative the meaning of such a word is in Muslim communities.
The bottom line IMO is that there is no easy nor painless future possible in the Middle East. I am worried that the article writer seems to hold significant hope that one might be found "if only" the USA could be convinced of "doing their part" by commiting troops with gusto to establish or keep "leadership in the region". I find that both unrealistic and undesirable, myself.
I think Israel is correct in being cautious. But I also think it is not being nearly cautious enough, nor non-militaristic enough.
