The potential strike by the United States against Syria, despite strong opposition from many countries and major political and religious leaders, including the pope, will result in more innocent victims and escalation, potentially spreading the conflict far beyond Syria’s borders. A strike would increase violence and unleash a new wave of terrorism. It could undermine multilateral efforts to resolve the Iranian nuclear problem and the Israeli-Palestinian conflict and further destabilize the Middle East and North Africa. It could throw the entire system of international law and order out of balance.

Syria is not witnessing a battle for democracy, but an armed conflict between government and opposition in a multireligious country. There are few champions of democracy in Syria. But there are more than enough Qaeda fighters and extremists of all stripes battling the government. The United States State Department has designated Al Nusra Front and the Islamic State of Iraq and the Levant, fighting with the opposition, as terrorist organizations. This internal conflict, fueled by foreign weapons supplied to the opposition, is one of the bloodiest in the world.

Mercenaries from Arab countries fighting there, and hundreds of militants from Western countries and even Russia, are an issue of our deep concern. Might they not return to our countries with experience acquired in Syria? After all, after fighting in Libya, extremists moved on to Mali. This threatens us all.

From the outset, Russia has advocated peaceful dialogue enabling Syrians to develop a compromise plan for their own future. We are not protecting the Syrian government, but international law. We need to use the United Nations Security Council and believe that preserving law and order in today’s complex and turbulent world is one of the few ways to keep international relations from sliding into chaos. The law is still the law, and we must follow it whether we like it or not. Under current international law, force is permitted only in self-defense or by the decision of the Security Council. Anything else is unacceptable under the United Nations Charter and would constitute an act of aggression.

No one doubts that poison gas was used in Syria. But there is every reason to believe it was used not by the Syrian Army, but by opposition forces, to provoke intervention by their powerful foreign patrons, who would be siding with the fundamentalists. Reports that militants are preparing another attack — this time against Israel — cannot be ignored.
