If we are to prevent ISIS from teaching us this lesson the hard way, we must acknowledge that we cannot extinguish the fires of fanaticism by force alone. The world must unite behind a holistic drive to discredit the ideology that gives extremists their power, and to restore hope and dignity to those whom they would recruit.  Read MoreCost of US campaign against ISIS is roughly $1 billion  ISIS certainly can – and will – be defeated militarily by the international coalition that is now assembling and which the UAE is actively supporting. But military containment is only a partial solution. Lasting peace requires three other ingredients: winning the battle of ideas; upgrading weak governance; and supporting grassroots human development.  Such a solution must begin with concerted international political will. Not a single politician in North America, Europe, Africa, or Asia can afford to ignore events in the Middle East. A globalized threat requires a globalized response. Everyone will feel the heat, because such flames know no borders; indeed, ISIS has recruited members of at least 80 nationalities.  ISIS is a barbaric and brutal organization. It represents neither Islam nor humanity's most basic values. Nonetheless, it has emerged, spread, and resisted those who oppose it. What we are fighting is not just a terrorist organization, but the embodiment of a malicious ideology that must be defeated intellectually.  I consider this ideology to be the greatest danger that the world will face in the next decade. Its seeds are growing in Europe, the United States, Asia, and elsewhere. With its twisted religious overtones, this pre-packaged franchise of hate is available for any terrorist group to adopt. It carries the power to mobilize thousands of desperate, vindictive, or angry young people and use them to strike at the foundations of civilization.

What most worries me is that a decade ago, such an ideology was all that Al Qaeda needed to destabilize the world, even from a primitive base in the caves of Afghanistan. Today, under ISIS, adherents have access to technology, finance, a huge land base, and an international jihadist network. Far from being defeated, their ideology of rage and hate has become stricter, more pernicious, and more widespread.  The destruction of terrorist groups is not enough to bring lasting peace. We must also strike at the root to deprive their dangerous ideology of the power to rise again among people left vulnerable by an environment of hopelessness and desperation. And, on this note, let us be positive.  The solution has three components. The first is to counter malignant ideas with enlightened thinking, open minds, and an attitude of tolerance and acceptance. This approach arises from our Islamic religion, which calls for peace, honors life, values dignity, promotes human development, and directs us to do good to others.  Only one thing can stop a suicidal youth who is ready to die for ISIS: a stronger ideology that guides him onto the right path and convinces him that God created us to improve our world, not to destroy it. We can look to our neighbors in Saudi Arabia for their great successes in de-radicalizing many young people through counseling centers and programs. In this battle of minds, it is thinkers and scientists of spiritual and intellectual stature among Muslims who are best placed to lead the charge.

It should be clear to everyone that the rapid growth of ISIS was fueled by the Syrian and Iraqi governments' failings: the former made war on its own people, and the latter promoted sectarian division. When governments fail to address instability, legitimate grievances, and persistent serious challenges, they create an ideal environment for hateful ideologies to incubate – and for terrorist organizations to fill the vacuum of legitimacy.  The final component is to address urgently the black holes in human development that afflict many areas of the Middle East. This is not only an Arab responsibility, but also an international responsibility, because providing grassroots opportunity and a better quality of life for the people of this region is guaranteed to ameliorate our shared problems of instability and conflict. We have a critical need for long-term projects and initiatives to eliminate poverty, improve education and health, build infrastructure, and create economic opportunities. Sustainable development is the most sustainable answer to terrorism.  Our region is home to more than 200 million young people. We have the opportunity to inspire them with hope and to direct their energies toward improving their lives and the lives of those around them. If we fail, we will abandon them to emptiness, unemployment, and the malicious ideologies of terrorism.  Every day that we take a step toward delivering economic development, creating jobs, and raising standards of living, we undermine the ideologies of fear and hate that feed on hopelessness. We starve terrorist organizations of their reason to exist.  I am optimistic, because I know that the people of the Middle East possess a power of hope and a desire for stability and prosperity that are stronger and more enduring than opportunistic and destructive ideas. There is no power stronger than that of hope for a better life.  Commentary by Sheikh Mohammed bin Rashid Al Maktoum, vice president and prime minister of the United Arab Emirates and ruler of Dubai.

If world leaders want to defeat ISIS, they will have to use more than force; they will have to win the intellectual war, says the ruler of Dubai.
