Nuclear Weapons in Russia

The United States and Russia control 95 percent of the world's nuclear weapons. The breakup of the Soviet Union left nuclear weapons sites scattered across Russia and the former Soviet republics. Since the, the United States and Russia have reduced their nuclear arsenals although both still retain thousands of nuclear weapons. With international aid, Russia recovered and then dismantled nuclear weapons from its former territories. In recent years, Russian support for nuclear power programs in Iran have led to renewed tensions between Russia and the United States.

Even while the United States and Russia agreed to further reductions in their nuclear stockpiles, many people worried about nuclear weapons falling into the hands of terrorists. Other nuclear nations, including India or Pakistan, were potential targets for terrorist groups seeking nuclear weapons. Securing all nuclear weapons and materials worldwide remains a top priority

Weapons of Mass Destruction

As you have read, weapons of mass destruction (WMDs) include nuclear, biological, and chemical weapons. Nuclear weapons include the atomic bomb. Biological weapons refer mainly to germs that can be released into the air or into water supplies. Chemical weapons are toxins, such as nerve gas and mustard gas.

Recently, the danger from WMDs has grown, as terrorist groups and “rogue states”—nations that ignore international law and threaten other nations—try to acquire them. NATO is working to prevent WMDs from reaching terrorists and has prepared recovery efforts if a WMD attack occurs. The U.S. and other nations also want to make sure that terrorists do not buy knowledge from WMD experts.

Investigators must wear protective gear in order to shield them from possible biological or chemical weapons.

The Growing Threat of Terrorism

Since the 1990s, the world has witnessed a growing threat from terrorism. Terrorism is the use of violence, especially against civilians, by groups of extremists to achieve political goals.

Terrorist groups seek to produce widespread fear. They use headline-grabbing tactics to draw attention to their demands.
