The radical left declared war on the US in the 1960’s.
They laid low for awhile and the war went hot again in 1991 with the R King video.
Instead of using domestic terrorist to fight their war like they did in the 1960’s, they enlisted the muslim terrorist as their proxy fighters.
Same tactics, orchestrate civil unrest then follow with terrorist attacks, just different people carrying out the attacks.
Right now they are orchestrating civil unrest/protest/riots as preparation for a major terrorist attack.
An attack likely fostered or promoted by our deliberately anti-American defense and immigration policies.
