US action against jihadists rests on politics, not law
Significance Senate Republicans have reopened the legal debate over the power of AUMFs and the ability of presidents to send forces anywhere at any time unilaterally. The debate has short-term implications for President Barack Obama's campaign against ISG, and also raises a number of constitutional issues that will shape the political debates surrounding Washington's use of military force against non-state actors. Impacts US anti-ISG activities in Libya will be limited to low-intensity drone attacks, airstrikes and special forces operations. Republican voters supporting Donald Trump will prove less supportive of intervention than party elites. Obama may accept a regime victory in the Syrian civil war to avoid domestic pressure for further US involvement.
