Brett, a Westerner who has joined the Iraqi Christian militia Dwekh Nawsha to fight against Islamic State militants, poses at the office of the Assyrian political party in Dohuk, northern Iraq February 13, 2015. Thousands of foreigners have flocked to Iraq and Syria in the past two years, mostly to join Islamic State, but a handful of idealistic Westerners are enlisting as well, citing frustration their governments are not doing more to combat the ultra-radical Islamists or prevent the suffering of innocents.
