No. It would have been different forces in the war. But, once Obama was out of power, ISSi was finished. You do know of the specific moment that the turning point happened. It was at a G20 (?) meeting in Europe, when Russia entered the war to back its ally, Syria. Putin and Obama had a talk in the lounge area of a hotel (?) and Putin told Obama to bomb the ISSI oil tanker trucks that they were using to haul oil to Turkey for refining. They sold the oil and financed the war. Obama would not bomb these tanker trucks, thus funding ISSI. Putin told him to either do it or he would. There are photos of Obama sulking on the couch because he knew his ploy was discovered. Obama did bomb some of the tanker trucks, but left most of them. Putin then bombed the rest of them, putting ISSI out of the oil business and starting the decline. And, that dear liberals, is why you are supposed to not like Russia. Obama was supporting ISSI and lying to you.
