I believe America's regime change operation in Iran will fail because Iran's government, military, and people are just too strong to be defeated short of all out war, which I doubt will ever happen. President Trump, and the American populace, do not want war with Iran or anyone else for that matter and there's no justification for war unless the US manages to fabricate one. Of course, Bolton, Pompeo, and the US military-industrial complex are rabid for war, but Trump is still the Commander-in-Chief of the US military, and war won't happen without his approval. So, the US regime change operation is limited to imposing economic sanctions, weather warfare attacks (evil), and propaganda campaigns that destabilize Iran's economy, create civil unrest, and indirectly leads to much death and suffering for Iranian civilians. But as I mentioned, I think, and certainly hope, it will fail.
