Al-Q isn't at 0%
Al-Q isn't at 100%
They're somewhere in the middle. Killing dozens of high ranking officials, yes, that does disrupt things. You can promote people, but replacing a terr'ist of 30 years like a bin laden isn't exactly easy to do, so even if the numbers are retained, the quality of bad guy is going to be lower.
Obama killed a lot of bad guys, and terror attacks have dropped since he took office. Coincidence? lol
