This is what happens if we go round bombing civilians and selling weapons to other countries who do the same. It breeds terrorism.
If we want our DC's future to be safer we need to stop voting for war mongers and people who profit - directly or indirectly - from the arms industry. It's not just Trump, it's people like Theresa May too, and Owen Smith for that matter.
Also having leaders who are serious about tackling climate change could make a huge difference. There is an environmental aspect to the troubles we're seeing around the world, see these articles for example:
Why Climate Change and Terrorism Are Connected
"U.S. military officials refer to climate change as a “threat multiplier” that takes issues like terrorism that would pose a threat to national security and exacerbates the damage they can cause."
GROWING CONNECTION BETWEEN CLIMATE CHANGE, TERRORISM AFFECTS POLITICS
"The military and intelligence communities agree that climate change is real and destabilizing."
Bill Nye: Paris Terrorist Attacks Linked to Climate Change
“It’s very reasonable that the recent trouble in Paris is a result of climate change,” said Nye, ... “There is a water shortage in Syria —small and medium farmers have abandoned their farms because there’s not enough water, not enough rainfall. And especially the ... young people have gone to the big cities looking for work."
"There's not enough work for everybody, so the disaffected youths ... are more easily engaged and more easily recruited by terrorist organizations, and then they end up part way around the world in Paris shooting people," Nye said.
" ... this is just the start of things. The more we let this go on, the more trouble there’s going to be. You can say, ‘We’ll stamp out the terrorists,’ but everybody’s leaving their farms because of water shortages, that’s a little, bigger problem.”
