i have the opinion that the U.S. is the only last superpower left in the world (except possibly China). and because of that, unfortunately, the allied support of the Coalition Forces is primarily symbolic more than anything.
that is not to undermine or discount the lives lost by coalition forces, however, without them, the United States military could still do its job. without the assistance of the Coalition Forces, the United States military could still be an effective combat unit and be able to achieve its mission.
of course, it is, and always has been, better to go into world conflicts with alllies. however, the amount of troops our allies have sent to the conflict is far less than they have sent in the past.
so, if the Italians remove their troops starting in September, so be it. The U.S. can still do the job there, with or without them.
i think we even have more U.S. security contractors over there than most of our allies' military troops.
just my two cents.
