It's not just liberals, but all levels of government that endorse the importation of terror. Hence the term "uni-party". The so-called 'conservative faction' played by the GOP reaps the benefits of greater military, police and security spending.
Chalmers Johnson wasn't a fan favorite @ FR, but he's been proven 100% correct about blow-back; specifically because it's the chosen technique used to ensure social disruption. There isn't any other logical way to look at what is happening in Europe & the US other than intentional determination to wage local war via foreign armies.
Even the military supports terrorism - if they didn't, why is a person committing bald-faced treason still walking around free? Besides, the response to blow-back ie further foreign intervention, is the key to making a successful career.
I sometimes feel that people are like cattle in a feed lot. They simply cannot believe what is occurring, will cling to their cherished beliefs, will quote an old parchment about some invention called "rights", and continue to allow denial to run deep, until the truth is revealed in a stunning moment of clarity.
I would say anyone involved is a liberal. It sure isn’t conservative or moderate.
