Question: Comment: Obama will be remembered for being the most divisive president of all history, tearing american society in two. He was 100% partisan, 100% of the time.  His failure to lead led to an 8 year standstill in Washington. He empowered Iran and North Korean to develop nuclear weapons, he created the perfect conditions for ISIS to conquer large swaths of the middle east, Russia to conquer Crimea, and China to take over the entire South China Sea, the largest sea conquest of all time. Still Obama managed to borrow more money than all other presidents put together, and US now owns more than 25% of the world debt, effectively guaranteeing the US' imminent decline and fadeout from 21st century history. Calling him the worst president in history is a woefully inadequate statement.

Answer:
Non-identity-attack
