The forces that make up this army are Muslims, not Muslim extremists, but Muslims following their master Mohammed and his book, the Koran.
According to the historical evidence, their founder, Mohammad was a pedophile-terrorist who used the sword as his great tool of persuasion and conversion. Their marching orders from the Koran demand that they lie to, kill and enslave us Infidels unless we convert by choice or by force to worship their false god allah and Mohammad his false prophet. (Sorry, I am not going to apologize for offending the sensibilities of Muslims because I have stated the historical facts.) Their stated goal in this war is to subvert, overthrow, destroy and subjugate every non-Islamic government (beginning with America and Israel) and kill, convert or enslave the citizen-infidels that make up their non-Muslim populations.
In their perverted minds and teachings, the legitimate targets of these attacks are Infidel civilians; non-combatants, women, children, ANYONE and EVERYONE, especially those who are NOT in uniform. Islamic terrorists tend to not fair all that well against national forces in uniform... they shoot back, where as women, children and guys in business suits and coveralls make easy targets. They don't have guns and usually have no concept of defending themselves from people who want to kill them.
I know the above is so un-politically correct and mean-spirited but these people are trying to kill us, our families and our nations.
From a Biblical-prophecy perspective we are living in wondrous and traumatic times... Jesus Christ is Lord and the true and living God, maranatha, come quickly Lord Jesus.
However, until He does come, stay safe, keep your eyes open, buy a weapon and learn how to defend yourself because you and I are the enemy in their eyes and war has been declared and unleashed upon us.
"If you have not a sword, sell your cloak and buy one."
