President Donald Trump said on Tuesday he will try again to stop fighting between Thailand and Cambodia after a ceasefire he helped broker in July collapsed this week. Trump, at a rally in Pennsylvania, listed the wars he said he has halted, when he mentioned the fighting between the Southeast Asian neighbors, which broke out again on Monday.

The self-styled “President of Peace” touts ending conflicts around the world. Renewed fighting in Cambodia is just the latest example of how many actually remain unresolved.
