As the West Asia conflict approaches its 200th day on September 16, the main question remains whether the states and players involved can convert battlefield pressure into a complete ceasefire or peaceful settlement. The conflict which began on February 28 this year with Israel and the United States unleashing massive strikes on Iran has expanded into a regional conflict epicentre with involvement of various regional parties, including Hezbollah in Lebanon, Houthi forces in Yemen, Hamas in Gaza and Iran-linked groups in Iraq. Civilian harm linked to the West Asia war has been recorded in at least 14 countries, according to conflict-monitoring organisation Airwars.
Paused, but no peace
Despite several diplomatic efforts and peace talks bids, the US-Iran ceasefire announced in April did not permanently resolved the conflict but temporarily reduced large-scale fighting. The White House said the April ceasefire ended the increased hostilities after 38 days of full-scale combat.
A more substantial breakthrough was followed in June, when the US and Iran inked a memorandum of understanding. The White House said the deal enabled an instant and complete stoppage of military operation and a framework for negotiations.
However, the underlying disagreement and conflict were not permanently resolved. The June MoU was followed by renewed military activity and subsequently expired. The Council on Foreign Relations states that the main disagreements entail specially over Iran’s nuclear disarmament programme, the Strait of Hormuz and sanctions relief were unresolved.
Why Diplomacy Failed?
The roadblock for permanent resolution of the conflict is because the war involves numerous interconnected disputes rather than just being fixated on the US-Iran confrontation. The US has urged for limits on Iran's nuclear and missile capabilities, while Iran has demanded security guarantees, sanctions relief and a complete end to military pressure.
The strategic importance of the Strait of Hormuz adds another layer of complication as it controls a major proportion of global oil and LNG shipments. Even on September 15, only four vessels transited the strait in one day, compared with a pre-war number of about 125.
The military cost for maintaining the war is rising, but cost alone has not yielded a settlement The US Department of Defense estimated the cost of the US war effort at $37.5 billion through the end of fiscal 2026, while the White House separately sought $87.6 billion in supplemental funding.
When is the End Expected Now?
Frequent diplomatic statements by US President Donald Trump and his Iranian counterpart prove that diplomacy remains possible, but no confirmed durable settlement is currently enforced. The recent continuing fighting around the Gulf and disruption of shipping coexist with the US continues to indicate interest in a negotiated truce or talks. Trump said recently that he expected the war to end later in 2026, but no final agreement had been secured.
Therefore, this signals a conflict that has moved from major conventional combat to an unpredictable combination of military pressure, intermittent negotiations and regional infighting. The immediate end of large-scale conflict is possible, but a lasting settlement depends on first solving the disagreements regarding nuclear issue, sanctions, regional security arrangements and control of Hormuz.
