According to this AP report:

More than 2,000 people have died in the provinces bordering Malaysia since the insurgency erupted in 2004, fueled by accusations of decades of misrule by the central government. The insurgents have not announced their goals, but they are believed to be fighting for a separate state imbued with radical Islamic ideology.

Thailand’s population is around 62 million, about a quarter of the US’s population. If we scale Thailand’s losses up to the US level we get 8,000 victims in less than three years. Thailand is suffering far more that the US has on a per head basis.
