In 1945, President Harry Truman ended the war in the Pacific, bringing about VJ day.
After dropping a bomb on Hiroshima, the Japanese continued to fight on without regard to any regard to morality. After Nagasaki (the second bomb) Emperor Hirohito surrendered. Subsequent to that, Gen. MacArthur took the formal papers of surrender and installed a Western system of Government in Japan. Japan has done handsomely since then, witness the death of Detroit vehicles in the U.S., not to mention TVs, radios, cel phones and every gadget one can think of.
Could this plan work in other places?
Maybe this time we stop after the jihadists are destroyed and defeated, instead of any largesse..
