I hope it's true. Middle east interventions have all led to failed state scenarios so far. And I doubt this administration is smart enough to do whats best for the US. End of day I guess Israel decides the outcome of this particular war. But yeah we will know in a few months.
To the best of my knowledge, yes. Iranian people are the most pro-West people in the middle east. It's in the US's interest to support them for a better future, and we've seen successful examples of this in the past in Germany, South Korea, Japan, etc.
Not every country should be compared to Iraq and Syria.
