Once again, President Trump exhibited the leadership and courage in challenging the accepted postulates and ignoring established rules and precedents.  The unwavering sense of the national interest led him to reconsider previous commitments to Afghanistan, Syria, and possibly Iraq.  After almost a generation of fighting in the so-called a "war on terror," with trillions of dollars spent and thousands of Americans dead and wounded, the questions are, are we better off now than we were seventeen years ago, when the war began?  Are the countries we engaged in better off today?  

Not so long ago, ISIS was marching in unrelenting waves of religious acclamation and territorial expansion, accompanied by terrorism and atrocities the world has not seen since World War II.  When Trump during the 2016 election campaign promised to destroy the caliphate "very quickly," he was mercilessly ridiculed by his opponents and the media.  In less than two years, Trump eviscerated the caliphate, cleared 99% of the territory, and killed thousands of fighters.

Nevertheless, despite this astonishing success, it would be utterly naïve to expect that the jihadi fanatics, who adopted an apocalyptic vision of the world and yearn for death, would cease perennial warfare and become productive citizens.

In this war, America and the Western world are facing a type of peril they have never faced before.  The immutable fact is that radical Islam is not just a religion; it is also a political totalitarian movement, just like communism and fascism.  The movement embraces religious supremacy and a Marxist-type utopian-egalitarian standard of virtue.  However, unlike communism and fascism, which were adopted by countries that could be defeated militarily, radical Islam is not a country; this mass movement represented by multiple groups is sustained by an ideology embodied in unlimited human resources around the globe. 

Another critical distinction is that this war also challenges the conventional definition of victory.  In a conventional war, the army loses if it does not win; in the war on terrorism, terrorism wins if it does not lose.  And it does not lose, because it has nothing to lose; the purpose of terrorism is not to win, but to terrorize, to break the will and paralyze the society into submission.

Hence, diplomatic solutions cannot be found, nor is it possible to defeat it in strictly military terms.

In order to face up to the enemy, we must recognize that the war with radical Islam is not just a military confrontation; it is also an ideological and a political affair.  First and foremost, this monster has to be defeated ideologically by superior principles advanced by Islam itself.

It is not a "mission impossible."  Some Muslim leaders are awakening to the realization that violence will not turn the clock, which the Arabs have invented, back to their greatness.  They find support among the majority of Muslims who adhere to a peaceful and pluralistic interpretation of their faith.  Indeed, Egyptian president Abdel Fattah el-Sisi has denounced Islamic terrorism and challenged religious clerics and scholars to "revolutionize the religion" and bring it in line with Western morality.

In his inspiring yet direct speech during his visit to Saudi Arabia in May 2017, Trump emphasized both countries' common interest in charting a constructive outcome.  He offered the Saudis, who spent billions spreading Islamic extremism across the globe, a choice: they had to decide whether they are a country respected by the world community or a cause.  At an October 2017 conference for international investors, Crown Prince Mohammed bin Salman responded positively by laying out Saudi's new approach to radical Islam: "We want to live a normal life ... coexist and contribute to the world[.] ... We will not spend the next 30 years of our lives dealing with these destructive ideas."  

Trump, on the other hand, is determined not to repeat the strategic blunders of his predecessors.  He is replacing fraudulent idealism with efficacy.  Trump's raison d'état in the relation to the Muslim world – keeping up the torch of international leadership – does not mean providing a security shield for the rest of the world.  The idealistic goal of removing tyrants and building democratic nations is incompatible with Islam.  Condemning Islamic radicalism and restraining the dogs of war, militarily, if necessary, is in the best national interest of the Muslim world.

In international affairs, the solution often leads to a new set of problems.  At this juncture, it is impossible to predict how an acceptable outcome can be distilled from the divergent political interests of Syria, Russia, Iran, Iraq, Israel, Turkey, and the Kurds.  However, the status quo that requires continued spending of lives and treasure cannot be tolerated by the American people.
