opel... drone warfare was a strategy implemented by the generals fighting terrorism against brown people who swore and dedicated their lives to kill Americans, in Syria and Yemen and later, Pakistan, during the latter stages of GWB's war in the middle east...they are much different from the brown people who love America and want to come to here for a better life for themselves and their families...don't believe Trump's claim that they are the same - he's lying...
drone warfare was considered a safe strategy to avoid putting American soldiers in harms way...using human assets (Arabs mainly, sometimes American operatives) on the ground to identify targets, armed drones were used to launch missiles at those id'ed as terrorists, their homes and their vehicles...
occasionally, Arab informants provided false identification to exact revenge against their enemies, who were not terrorists but people who committed some offense against the informants...errors in identification or execution were made... innocent people in the houses or traveling with a known terrorist were killed...
Obama inherited this operation and the two generals who developed the strategy, McCrystal and McRaven...and went all in...it resulted in hundreds of terrorists being wiped off the "most wanted" list, especially in Pakistan, but also some terrible mistakes, like the wedding parties that got blown up without any of the dozens of people killed having any links to terrorism...but considering the number of civilians killed during traditional warfare, this was considered an acceptable alternative...
we are coming under increasing pressure by the UN and world peace advocates to end this practice, especially because innocent people are continuing to get killed ...
btw...drones are still being used by the Trump administration, but not openly advertised as during the Obama terms, and deserves some credit for taking down ISIS ops in Syria and Yemen...too bad they couldn't have nailed the ISIS guys in Sri Lanka before they blew themselves up...
