We are not presently in a time for peace.
Suddenly, it appears, the poor and disadvantaged from failed states in the Middle East, North Africa, and elsewhere have decided that the western world is where they want to be, and they have a right to be there. Curiously, the vast majority of these people are young men of military age, and ISIS leaders have been bragging for months that they will be sending undercover fighters to Europe and the Americas to destroy us, "the infidels" : Link
These young invaders will sire children quickly, and the hundreds of thousands who come now will be millions as the years pass. The present stream of "refugees" will become a flood in days to come. Besides, we westerners have already accepted millions of these people over the years. Their numerous angry children have grown up hating their host countries, and the west in general. Scandinavia, France, and Belgium have huge problems with these criminal youths. Many jihadist mass killings have been perpetrated - as were the Paris attacks in January and November - by these second-generation Islamists; even those whose parents deplore their actions and don't hate us.
Why don't these millions of discontented men of military age stand up and fight for their own nations? For thousands of years, men who wouldn't do this were called cowards, and they were shamed and disgraced for their weakness. Do we have an obligation to help these strong, young men escape their moral obligation to stand and fight for their own countries, and what they say they believe in?
We non-Muslim peoples and nations of the world are at war with radical Islam, and not by choice. A religious reformation (much like ours in the 1500's) has shaken 1.5 billion Muslims all over the globe, and according to reliable polling, half want Shariah Law, the brutal, Medieval code which has made so many Muslim countries backward and miserable. Almost a fourth (375,000,000) have said they are justified in taking up arms against those who don't pray to Muhammad: Link and Link
The freedoms we enjoy, and which have made the western world so rich, pleasant, and attractive are slated for destruction by these anti-Judeo-Christian-Buddhist-Hindu hordes. They're savage purveyors of mayhem and murder, and proud of it. But we people of other religions outnumber them at least four-to-one.
A core belief among Sunni and Shia Muslims (who make up more than 90% of Islam) is that there's a Twelfth Imam, "The Mahdi", coming to earth soon. Like Christ, but supreme over Christ, he will remake the world and destroy its evils: Jews, Christians, Hindus, Buddhists, and other "apostates" who will not submit to Allah's word. Believers in the Mahdi preach that violently overthrowing the western world and destroying all who stand in the way of their violent vision of Islam, their so-called "jihad", will cause the 12th Imam to appear sooner, and make the world a paradise.
Millions of westerners, and most of their leaders, refuse to believe what Muslims tell them openly, and they're ignoring the hideous violence and destruction that have already laid waste to the cities and nations who harbor these jihadists. We face a "sea of somnambulists", sleepwalkers who will get us killed by their inaction.
Civilization is a delicate thing, and when broken, may never return to a civilized state. Look at the former colonies of the once-great powers throughout the world. Many of today's failed states were prosperous former colonies: Somalia, Zimbabwe, Ivory Coast, Lebanon, Venezuela, Argentina, etc.
Pray, and prepare yourself and your country for defense, according to your wide-awake conscience.
