After the Boston Marathon bombing, when word spread that the Russians notified our intelligence agencies, I was thinking :
"Yeah , right, sure, whatever… "
I had held paradigm that the Russian government wanted the USA to fall to communism.
Russian support of our recent Middle East, Africa, and Central Asia expeditions have been tepid and secondary at best.
They may share a commonality that Islamic militants are causing problems in their towns
as they have done and attempted over here.
Not sure if our intelligence staffers were also in the same old Cold war paradigm of general distrust towards the Russian agents.
I mean , they did interview the older brother after some tips.
And I assume the US State department would have raised a big international case on the Russians if they detained the older brother when he visited.
The situation for our authorities is almost like Vietnam before our troops pulled out.
There not much of a human way to tell who (Russians, Cypriots, Germans, French, Chinese, Mexicans, Canadians, Chicagoans, or Islamics) is just pretending to be your friend
Last I checked , the Russians were moving towards totalitarianist Communism again w Putin.
But then again , the Russians see an enemy in militant islamics, who hate the USA as the little satan, therefore, we are their friends again.
