Unless you have inside information you have no
true knowledge about 'their intention' and as for " ride rough-shod over all in their path, even to the shores of Europe" that is unthinking panic-mongering.
There are several very well equipped armies towards 'the shores of Europe' , the US have dozens of military bases in the Middle East and have shown the world many times that they will invade to protect US citizens (Erbil protected before Mount Sinjar) , and Obama just reiterated the NATO doctrine in Tallinn Estonia this week, of "an attack one is viewed as an attack on all."
"Krom, the potential causes haven’t been ignored; they have been discussed ad infinitum." ................. have they? Did they discuss how the entire Middle East is a Western construct created and supported by the West to ensure one thing flows? Not honesty nor democracy but OIL.
Do you honestly believe that the US with agents and global satellite and communication surveillance and bases spread all over that territory were 'unaware' of this ISIS threat growing?
Keeping the Middle East states/groups at each others throats suits the Western interests that foster(ed) it.
The US and world at large knows that the Saudi exportation of Wahhabism has stoked these fires and the West used and funded this Wahhabism to fight the Russians in Afghanistan.
Do do you expect your leaders to willingly eradicate a menace that they are complicit in and have been complicit in for so long when it still suits their agenda ?
Ending this 'threat' permanently would involve military action in several Africa countries, libya, Iraq, Syria, Saudi Arabia, Kuwait, Jordon, Quatar,Bahrain, United Arab Emirates, etc Puppet Dictator etc.
That would probably lead to a worldwide war which no sensible person would want.
United Nation NOT Nato should lead a coalition of forces to eliminate the ISIS threat in Iraq, Syria, Libya, and leave an overwhelming military presence in Iraq for the foreseeable future. The Saudi exporting of Wahhabi extremism must be stopped with sanctions and the seizure of all their plentiful Internationally held assets.
All support for the Family of Dictators in the Middle East should end.
I honestly do hope you enjoy your relatively privileged 'standard of Living' but have the honesty to recognize its true cost.
