Come reagirà la leadership iraniana qualora gli Stati Uniti dovessero attaccare la Siria? Qui l’analisi della Reuters:

[…] “The Syrian crisis is as polarizing for Iran’s political elite as it is for the international community,” said Yasmin Alem, a senior fellow at the Atlantic Council’s South Asia Center. “It is no longer clear whether Syria is the lynchpin of Iran’s security or a threat to it.”
Much depends on the intensity and extent of any U.S. attacks on Syrian government forces and facilities. “A limited attack with minimum impact on the balance of power in Syria is unlikely to impede nuclear diplomacy with Iran,” said Ali Vaez, senior Iran analyst at the International Crisis Group.
“Rouhani’s success depends on rescuing Iran’s ailing economy, the realization of which is nearly impracticable without sanctions relief. If he allows Syria to spoil the nuclear negotiations, his presidency will falter just one month after it began.”
