First, the US and Western Counter insurgency operations are failure, because frankly, in simple words, we are too good and pussyfooted. We are not brutal enough.
I have previously written why Western strategies fail, and stated that in the last 20 years, only two Counter Insurgency operations succeeded, and that’s in Sri Lanka, and Chechnya. It was brutal, but it brought on stability.
Latest research proves, the only way to succeed in a COIN op, is to be insanely heavyhanded.
