the fake left parties in canada are currently run by very stupid people. that wasn't always the case. the reality is that they're running against the iraq war, which this is definitely not, and which nobody thinks it is.
should israel take out iran's nuclear facilities? this is not a helpful question. if they could do it on their own, they already would have.
the real question is whether the united states would do this, and it has not been american policy for the reason that it would be very difficult. these facilities are cut into mountains. the americans have preferred to use the iaea because it's more effective.
that said, israel does have an active policy on the issue, which is sabotage. the israelis have used cyberwarfare, assassinations, infiltration, etc to slow the iranians down. this is the approach the israelis will continue to use until or if the americans order a strike and that will depend largely on whether they think it will work or not.
