It’s been an uneasy partnership. After months of frustration on both sides, the U.S. has announced a suspension of talks with Russia about bringing peace to Syria. The move comes just days after the U.S. government threatened to break off their fragile bilateral partnership. Their reasoning? Russia and the Syrian government bombed Aleppo heavily this weekend, shattering hopes of an extended ceasefire – and allegedly deliberately targeting humanitarian aid convoys. The U.S. has also made it clear they won’t be cooperating with Russia’s military any time soon. “This is not a decision that was taken lightly,” said a State Department spokesman.
