Unilateral military force will merely destroy both the United States itself, and the alliances we have worked so hard to form.
Contention One: Military force spurs countries to develop nuclear capabilities
Butt, Yousaf, Christian Science Monitor, 9/5/2012, http://www.csmonitor.com/Commentary/Opinion/2012/0905/AnVIsraeliVstrikeVwonVtVdelayVIranVsVnuclearVweaponsVprogram.VItVwillVstartVit) Yousaf Butt, a nuclear physicist, is professor and scientist-in-residence at the Monterey Institute of International Studies.
If we allow military forces to go into a country and attack, then we are giving that country a reason to come after the United States. As a result, that country will be more determined to make nuclear weapons and our plan would have backfired. We look to history to for support here: In 1981 Israel launched an attack against Iraq. Iraq responded by developing a nuclear reactor complex. Saddam Hussein then demanded nuclear deterrence and was the actual trigger for Iraq launching a full-scale effort to weaponize. A decade later, by the time of the 1991 Gulf War, Iraq was on the verge of a nuclear weapons capability.
Malfrid Braut-Hegghammer explains,
“Preventive attacks can increase the long-term proliferation risk posed by the targeted state.”
Therefore, Military force will cause failure rather than success.
Contention Two: Non-military intervention is more effective
