The report describes internal contingency planning. It does not establish that Iran has selected those targets or approved an attack. That distinction matters at a moment when military warnings and diplomatic proposals are circulating at the same time.
The response being discussed
Reuters based its account on three senior Iranian officials and an insider familiar with the discussions. According to the report, commanders are examining how to make a future response more extensive if Washington launches another major round of strikes.
The possible expansion has two dimensions: which countries could be affected and how far beyond the current regional confrontation a response might reach. The accessible account does not name a specific country or location outside the Middle East. It therefore does not support a list of threatened European cities, bases or infrastructure.
A plan tied to renewed attacks
The trigger described in the reporting is renewed large scale American military action. Discussion of possible retaliation does not, by itself, establish a decision to begin a separate war or a timetable for an operation.
Earlier reporting about possible Iranian attacks on U.S. facilities in Europe provides background, but cannot identify the targets in the latest discussions. Combining the two accounts into one confirmed operational plan would go beyond what has been reported.
Diplomacy remains part of the picture
The military deliberations come as efforts to reach an understanding with Washington continue. Reuters described little confidence among its sources that diplomacy would produce a breakthrough, while Trump has rejected Iran's latest proposal as insufficient.
Pessimism about negotiations is an assessment attributed to those sources. It does not mean that talks have formally ended. Governments can maintain diplomatic contacts while examining military options, and the existence of one channel does not establish the outcome of the other.
What the report leaves unresolved
No public operational order or final target list was presented in the reporting. The account also does not establish which options, if any, have received approval from Iran's highest decision-makers.
The significance is the reported breadth of the deliberations: countries supporting American operations could face consequences beyond the immediate battlefield. Whether those possibilities become policy remains unresolved. For now, the development is a reported widening of Iran's contingency planning, rather than an announced expansion of the war.
