Challenges to resolving issue of WMDs
Armed conflict
21st century arms race
Shortcoming of international law
Armed conflicts challenge
increases justification for wmd use and proliferation for security guarantees'
US - Iran conflict, Feb 2025 - Iran informed IAEA that normal safeguards were “legally untenable and morally impractical” due to “acts of aggression”
US and Israel commenced military strikes on Iran of the 28th of February 2026
21st century arms race challenge
“new arms race” is driven by geopolitical tension
as of 2025, all 9 nuclear states are modernising their arsenals as evidenced by 2.7 T global military spending 2024
trump “equal basis”
US increase nuclear spending by 10.3% in 2024
shortcoming of int law challenge
treaties rely on state cooperation and lack strong enforcement mechanisms'
Political stability
Mutually Assured Destruction (MAD) - weak as based on tensions and cause some instability like US - Iran conflict
no new recorded nuclear states in last two decades
NPT strength + popularity
Political change
revival of nuclear testing - trump, DPRK
collapse of New Start
sparking of armed conflicts
global interconnectedness
+The UN - enforcement of NPT and IAEA, fosters global discussions on how to effectively eliminate the threats of WMD
-Conflict escalation beyond borders
