Your analysis is pretty much correct, but if I were setting up for a major attack, I'd have the foot soldiers in place, if there was no resistance, and ready to move when the time came.
Currently, America is witnessing an invasion and if the truth was being told, this invasion is an invading army. I have no doubt an army is being slipped into the United States, right under our very noses, and our politicians are doing nothing to protect US citizen, instead those politicians are aiding the army as it positiions itself. This is why I've said the majority of our politicians have the "on bin laden's payroll syndrome". bin laden has to be laughing his butt off as the invading army positions itself for the next attack.
