AllStances: Should the US Intervene Militarily to Prevent Adversaries from Acquiring Nuclear Weapons/WMDs?

In the wake of Donald Trump’s bombing campaign targeting Iran’s nuclear facilities, many are drawing parallels to George W. Bush’s invasion of Iraq over weapons of mass destruction (WMDs) – and asking: is it justified for the U.S. to intervene militarily to prevent the spread of nuclear weapons or other WMDs?

Stance 1: The US has a moral and strategic obligation to prevent adversaries from acquiring nuclear weapons

Core Argument: The US, as the world’s global protectorate, has a moral duty to use necessary hard power, overt or covert, against sovereign nations if said nation is potentially developing WMDs or nuclear weaponry and may be of threat to the region or world.

Supporting Arguments:

• Hostile states like Iran should not be able to develop nuclear weapon technologies; at all costs. The capacity for devastation justifies attacks or bombings to prevent their development and proliferation.
• “Iran's quest for nuclear weapons is a major threat to our nation's national security interests. We can't allow Iran to go nuclear”, said Donald Trump in 2011.
• A report in 2025 by the UN’s nuclear watchdog agency found that “Iran conducted secret enrichment activities at three facilities and has amassed enough uranium at near-weapons-grade levels to make nine nuclear bombs,” which poses a grave threat to the region and world, justifying military action.
• A well-timed preemptive strike can halt an aggressor and prevent a dangerous, potentially life-threatening confrontation from escalating.
• The US, as a signatory of the Non-Proliferation Treaty (NPT), is expected to help prevent nuclear proliferation. The US is also expected to act decisively and sometimes forcefully when adversaries violate the NPT or develop covert programs.
• Historically, preemptive strikes such as Israel’s attacks on an Iraqi nuclear reactor (1981) and a reactor in Syria (2007) have successfully prevented the development of nuclear technologies in hostile nations.
• The protection of allied nations from WMDs justifies hard intervention.

Stance 2: The US should never intervene militarily to stop nuclear development

Core Argument: The US should never attempt to militarily intervene overtly or covertly in a sovereign state’s affairs, even if there is a threat of WMDs. The US does not have a right to use hard power against a state, especially without congressional approval.

Supporting Arguments:

• The most notable military intervention over WMDs in the 21st century was the Iraq War (2003), which was a failure due to the absence of WMDs and the overall failure of the state after a violent insurgency arose. Preemptive attacks often fail or backfire.
• Unilateral military action may violate the UN Charter and international norms on state sovereignty, which may tarnish global reputation. The 1981 Israeli bombing of an Iraqi nuclear reactor was condemned by the international community.
• Multinational agreements such as the Agreed Framework with North Korea have verifiably limited nuclear programs through diplomacy. While Iran no longer abides by the Iran Nuclear Deal (JCPOA, 2015), both the US and Iran have said in the past that “they would return to the original deal” if terms can be agreed upon.
• Tensions in regions like the Middle East have a capacity to spiral out of control, where striking a nuclear facility could spark terrorist attacks, insurgencies, regional war, or even global conflict. Economic concerns such as oil disruption could also raise prices and strain economies around the world.
• Military intervention over WMDs, such as the Iraq War (2003), have significant unfavorability retrospectively, with over 60% of Americans and veterans saying the Iraq War was not worth fighting. Similar trends exist for military intervention in Libya (2011).

Stance 3: Military intervention should only occur with verifiable evidence and congressional authorization

Core Argument: The US should only consider engaging militarily with a sovereign state if a threat of WMDs can be verified without a shadow of a doubt. Congressional approval should be required for any military action.

Supporting Arguments:

• Insisting on verifiable intelligence would allow for necessary intervention against real threats while also preventing costly mistakes like Iraq (2003).
• Iran (2025) passed inspection with the International Atomic Energy Agency (IAEA) and had no nuclear weaponry. Even after the bombings, Iran can potentially rebuild their nuclear program within months.
• Requiring congressional approval for military action reinforces the War Powers Resolution and ensures that major action reflects the will of the American people. Congressional debates over Libya (2007), Syria (2013), and Iran (2020) reflect the necessity for dialogue and agreement among constituents and representatives.
• Internal checks and balances legitimize intervention, reinforcing international alliances and cooperation. US involvement in Kosovo (1990) and Iraq during the Gulf War (1990-1991) were joint operations backed by NATO and coalition forces. These conflicts were generally more well received among the international community as they were grounded in multilateralism and legal authority.
• The transparency of intelligence before military engagement often helps to maintain public trust and international support. Prior to the Russian invasion of Ukraine, the US “made eight disclosures refuting Russian propaganda and exposing the Kremlin’s plans for a full-scale invasion of Ukraine”, which has served as a transparency model to precede conflict.
• Strategic restraint would allow US military strength to serve as a deterrent while also improving long-term credibility by avoiding “forever wars”.
• Congressional approval would prevent abrupt changes to global power dynamics whenever a new president is elected.
