US Army Air Corps B-17 Flying Fortress dropping "dumb" bombs
on Germany in World War II
During World War II and for decades after, "dumb" or unguided bombs were the only way to put explosives on target from the air. Beginning in the Gulf War, America and other nations started using "smart" or guided bombs.
In 1999 when American B-2s bombed Belgrade, Pentagon spokespersons said they could not only hit a specific building, but put a bomb in a specific doorway of a building.
Beginning in September 2015, Russian strategic bombers flew from Ossetia near the Republic of Georgia in Southern Russia and bombed targets in Syria. They claimed to be fighting ISIS, but hit civilian targets, causing thousands of casualties. The Russian bombers dropped "dumb" bombs. Various news outlets at the time speculated that the Russians used dumb bombs because these bombs are much cheaper than guided weapons. Up to 100 times cheaper. The Miami Herald wrote this.
In his book The Road to Unfreedom Timothy Snyder said Russia began bombing Syria three weeks after Germany announced it would take in a half million refugees.
"Russian aircraft dropped non-precision ("dumb") bombs from high altitudes. ... Russia was not targeting ISIS bases. Human rights organizations reported the Russian bombing of mosques, clinics, hospitals, refugee camps, water treatment plants and cities in general." (pages 198-199)
Dumb bombs made the refugee crisis worse. Putin's goal, according to Snyder, was to destabilize Europe. By making the refugee crisis worse in Europe, the Russian bombing campaign played to the xenophobia of the fastest-rising candidate in the American Presidential election. That candidate would eventually take the side of Vladimir Putin over his own intelligence agencies.
The dumb bombs were dropped by a man with a smart plan.
