Yes, #1, I don't think neither israel nor US has the ablity to contain Iran at this point of time unless US wants the entire destruction of its soldiers in the ME and complete destruction of israel. US is in very difficult position again regarding its internal politics here in the USA. So, don't worry nothing is going to happen and Ayatollahs can have a sound sleep while they are smiling both at israel and USA now a days, look at israel and white house now.
