This is a western take on the situation. Another take would be that the US/Israel are the largest force for destabilization in the middle east (see also Iraq, Afghanistan, Syria, Lebanon, Libya, and Iran itself from 1953-onward).

The west would absolutely lose a ground war in Iran. Iran has been preparing for an invasion for 50 years, the terrain isn't like other countries in the region and is incredibly hostile to a ground invasion, and the IRGC will fight to the bloody end (see also the Iran-Iraq war).
