Will Iran Become Another Forever War?

TL;DR

The Iran war risks becoming prolonged because neither side has achieved decisive goals, yet escalation threatens a catastrophic global energy crisis.

Key Points

• 1.Iran's missile and drone capabilities have been significantly degraded but not eliminated. The US destroyed one-third of Iran's missile arsenal, Israel eliminated 290 of 410–440 launchers, and a third of drone capability was destroyed, yet Iran still launches ~30–35 missiles and 70 drones daily on average.
• 2.Total energy war remains the key mutual deterrent against full escalation. Iran's South Pars gas field (70–75% of gas production) and Kharg Island (90% of oil exports) are spared; in retaliation Iran could destroy Gulf desalination plants, Ras Laffan, and Saudi pipelines, triggering a global energy crisis.
• 3.The strongest argument for a short war is political and economic pressure on the US. Trump stated the US would be 'out of Iran pretty quickly' within 'two or three weeks'; Rubio narrowed objectives to missile/drone facilities and air force, deliberately omitting regime change or full nuclear dismantlement.
• 4.Israel's stated goals make a quick exit strategically difficult. Netanyahu outlined three objectives on March 19: removing the nuclear threat, eliminating the ballistic missile threat, and creating conditions for regime change — none of which have been fully achieved, incentivizing Israel to continue.
• 5.The sunk-cost fallacy and Iran's survival create pressure for a longer war. If the regime survives, it will likely become an IRGC-led military dictatorship focused on rebuilding military capacity, potentially aided openly by China and Russia, meaning stopping now could simply delay a future conflict from a stronger position.
• 6.The Strait of Hormuz closure is the single biggest obstacle to ending the war. A senior Iranian official told Reuters the Strait 'will never return to its former status, especially for the US and Israel,' and Iran refused to reopen it for a temporary ceasefire, making US withdrawal without a deal a major reputational blow.
• 7.Ceasefire talks have stalled and escalation continues as of early April. Pakistan brokered talks, a ceasefire was announced April 8 but with incompatible frameworks; Israel then struck Lebanon in its biggest raid of the war, Iran re-closed Hormuz, and on April 12 VP Vance left Pakistan with no agreement as Trump threatened a full naval blockade.
