The Future of US Counterterrorism Efforts in Yemen Is Uncertain
The US has been gravely compromised due to its backing for a Saudi-led coalition in Yemen. Military action alone will neither bring peace to Yemen nor protect the United States from the problems it aims to address. Anti-Houthi infighting has hindered counterterrorism operations. Critics have expressed grave reservations about the lack of domestic legal power. The withdrawal of the majority of the US backing for the Saudi-led coalition in Yemen resolves many significant issues under international law.
Saudi Arabia and the United Arab Emirates have been accused of several war crimes throughout the deadly battle against the Houthis. Yemen is one of several long-running fronts in the “eternal war,” with AQAP and IS remaining relatively silent for the time being.
