executive authority

After reading The War Powers Resolution: After 30 years and Authorization for the use of Military Force in Response to 9/11 attacks, explain how executive authority to commit U.S. Armed Forces changed after 9/11.  Building from the course readings and your own research, identify at least two key differences in the way the U.S. employed military force after 9/11.  Finally, do you believe the executive branch should have greater liberty to ally military force post-9/11?  

Your initial post should be at least 250-300 words in length. Support your claims with examples from required material(s) and/or other scholarly resources, and properly cite any references.
