The United States and Iran traded new missile barrages Thursday, reviving the cycle of retaliatory attacks that has shaped their five-month conflict. The renewed exchanges followed a short lull, but the pause did not produce any clear sign that the confrontation was moving toward a fast settlement.

The latest strikes suggest that the pattern of action and response is taking hold again. With each side launching fresh attacks, hopes for a quick resolution have faded and the prospect of near-term de-escalation appears more uncertain.

The return to missile fire has also intensified concern that the fighting could expand beyond its current scope. After several calmer days, the renewed exchanges have fueled fears that the conflict may broaden into a wider war.

The new round of attacks highlights how fragile any respite has become in the US-Iran standoff. After five months of conflict, the situation remains highly volatile, with even a brief break in fighting offering little assurance of lasting calm.
