I agree more could have been done early on but the enemy has gotten better as well. I wish countries around both war zones would do better at restricting such easy movement by these insurgents. This is where Iran, Syria, and Pakistan play such big roles in both wars because the access is there. The Syrian border should just be shut down along Iraq's border period and if anything moves during the night just blow it up. Nothing stops these outsider from landing in Syrian airports and just making there way to the border. Pakistan doing a horrible job at sealing their border if it were Indians trying to get in not one would make it.
