Back when the west were fighting a proxy war in Syria, Israel was trying yo get the Syrian anti-air systems to target civilian traffic. They did succeed in getting them to down a Russian troop carrier iirc by using the tactics as they wanted to escalate tensions.
It is an escalation but it does matter if it was in Iranian airspace or not. If it was in Iranian air space then it's escalation by the US, if not in Iranian air space it's escalation by Iran. The US has said, and I provided the video earlier, multiple times that it wants to provoke Iran into a conflict either by confrontation or false flaging them, which is what I think happened with the tanker bombing.
Sanctions are the other major form of provocation that Iran has had to sustain for the last years, Iran can just trade with the BRICS countries and bypass a lot of those sanctions. Nobody has the right to tell another country what they should do, in an ideal world, and the US/Israel should keep their noses out.. It's ironic that the only reason that Iran feel the need to go for nukes, which Israel is having a fit about, is because of the US/Israeli aggression that's been happening for years!
