They have invaded plenty..they just do it in a different way.
Much of sub-Saharan Africa is now Muslim, the Phillipines is in danger, Sri Lanka, Indonesia and countless others. How many Mosques are in France, Denmark, the UK, Canada,
and yes, now the US !..that were not there 50 years ago ?
Remember, other faiths are either not allowed or for the most part, treated like dirt in Islamic countries
They do not always invade carrying rifles and hand grenades, at least not to start ! First, they move into "free" societies..spread their poison, capturing simple minds,
and surely, simple minds can be dangerous..it only took 19 of them to put our nation into a world of hurt ! Yes, some of them were "educated", but they were still
simple (to kill themselves for a pedophile's promises).
First, they win over enough dimwits and opportunists to create upheaval in a country..then they start with the rifles, hand grenades, IEDs and etc. look at the Sudan,
Afghanistan, Iran etc..Witness what is happening in Lebanon as we speak !
Assassination is nothing new to them...having originated the very word "assassin"...
