The United States and Iran continue to experience long-term tension following a military campaign started by the U.S. and Israel on February 28, 2026. Current efforts are focused on negotiating a peace treaty and a new nuclear framework to replace the failed Joint Comprehensive Plan of Action (JCPOA).

在美國與以色列於 2026 年 2 月 28 日發動軍事行動後，美國與伊朗之間持續處於長期緊張狀態。目前的重點在於協商一份和平條約及一個新的核框架，以取代失敗的《聯合全面行動計畫》(JCPOA)。

The current political deadlock began when the U.S. left the JCPOA in 2018. This 2015 agreement was designed to limit Iran's nuclear growth through strict monitoring and limits on uranium enrichment. President Donald Trump has claimed that the JCPOA was fundamentally flawed and argued that it would have allowed Iran to develop nuclear weapons. In contrast, security experts emphasize that the deal successfully stopped nuclear growth and provided a high level of transparency. Since the U.S. withdrew, Iran has increased its uranium enrichment, with stockpiles reaching nearly 21,800 pounds by June 2025, including material that could be used for explosives.

目前的政治僵局始於美國在 2018 年退出 JCPOA。這項 2015 年的協議旨在透過嚴格監控與限制濃縮鈾來限制伊朗的核發展。川普總統聲稱 JCPOA 根本存在缺陷，並認為這將允許伊朗開發核武。相反地，安全專家強調該協議成功阻止了核發展並提供了高度透明度。自美國退出後，伊朗增加了濃縮鈾，截至 2025 年 6 月，儲量已接近 21,800 磅，其中包括可用於爆炸物的材料。

Military tensions increased on February 28 with joint U.S.-Israeli strikes that killed Supreme Leader Ali Khamenei and other top officials. Some analysts believe this was an attempt to change the Iranian government. Consequently, Iran blocked the Strait of Hormuz, which disrupted about 20% of global oil supplies and caused prices to rise within the U.S. Although a ceasefire was reached on April 6, a final diplomatic solution is still missing. President Trump has stated that any new agreement will be better than the JCPOA. However, negotiations are currently slowed by disagreements over the timeline for reducing enriched uranium, as the U.S. proposes a 60-day window while Iran asks for 90 days.

軍事緊張局勢於 2 月 28 日隨著美以聯合襲擊而升級，導致最高領袖哈梅內及其他高官喪命。部分分析師認為這是試圖改變伊朗政府的嘗試。因此，伊朗封鎖了霍爾木茲海峽，導致約 20% 的全球石油供應中斷，並引起美國國內價格上漲。儘管 4 月 6 日達成了停火，但仍缺乏最終的外交解決方案。川普總統表示，任何新協議都將比 JCPOA 更好。然而，由於在減少濃縮鈾的時間表上存在分歧，目前談判進度緩慢，美國建議 60 天窗口期，而伊朗則要求 90 天。

At home, the conflict has become a political problem. Polling data shows that a majority of voters believe the intervention is harmful to national interests. Furthermore, this dissatisfaction is made worse by the economic impact of unstable energy prices. Despite these pressures, the administration has remained calm, with President Trump asserting that preventing Iran's nuclear capability is the main goal, regardless of the upcoming elections or domestic financial changes.

在國內，這場衝突已成為一個政治問題。民調數據顯示，大多數選民認為此次干預對國家利益有害。此外，能源價格不穩定所帶來的經濟影響加劇了這種不滿。儘管面臨這些壓力，政府依然保持冷靜，川普總統堅稱，無論是即將到來的選舉還是國內財務變動，防止伊朗擁有核能力仍是首要目標。

The U.S. continues to seek a full diplomatic settlement with Iran. However, the process is complicated by a history of distrust, different views on nuclear timelines, and falling public support for the conflict.

美國繼續尋求與伊朗達成全面的外交解決方案。然而，由於歷史上的不信任、對核時間表的不同看法，以及公眾對衝突的支持度下降，使得過程變得複雜。
