Based on the verified information available, the claim is incorrect. Here is the analysis:

Reasoning:

• The United States and Iran reached a preliminary agreement (memorandum of understanding) on June 15, 2026, not a permanent peace treaty¹. It is explicitly described as "an initial framework and not a final peace agreement"¹.
• The agreement establishes a 60-day ceasefire period during which further negotiations are expected to address unresolved issues, including Iran's nuclear program¹. This is not a "permanent" end to military operations.
• The agreement is described as extending a "shaky ceasefire" that has been violated numerous times by both sides since its declaration².
• While the deal does include ending hostilities in Lebanon, it is a tentative agreement, not an "immediate and permanent end to military operations on all fronts"³⁴.
• Previous claims in the verified database confirm ongoing conflict as recently as April 2026, with Iran resuming the blockade of the Strait of Hormuz and the war continuing⁵.
