@bobsal u1553115,
It would solve nothing in the mean time as ISIS wouldn't be swayed by weakness, and that is really what you and Obama bring to the table. You really have no idea how to work against terrorism do you? Leaving them alone doesn't work as we have already done that and ISIS is spreading across the ME like cancer. The only reason they are armed so well is because Obama couldn't wait to get out of Iraq and in the process forced the military to leave things behind. Terrorism in Iraq was on the decline prior to Obama taking office, remember the surge? Since that time Obama has claimed victory and success in Iraq, which turned out to not be true, and even claimed hours before the Paris attacks that ISIS was contained, which also turned out to not be true. Tell the people of Paris that ISIS is contained and they would laugh in his face. As a military leader, Obama is a joke and I'm sure a majority of the military doesn't even respect him.
In this day and age of radical terrorism, to claim climate change is the greatest threat is laughable. Bernie Sanders even doubled down on that claim.
