Maybe an almost “a redundant statement”. Though, noteworthy.
Those Zoroastrians, were not simply a “tribe”. Zoroastrians *firmly* held a very notable & powerful country (Iran) for many many centuries prior to Islam & even before Christ was born & Christianity as well. Judaism, also, was mainly a faith, but held no significant power in land, for all those times.
Islam is & has been after “Land” & more importantly “Power” that flows from it — it uses its ideology/doctrine (we also call it ‘religion) to do so. Very similar to Communism or Socialism of USSR.
So now, they are after those “Lands” (countries) that are traditionally & currently known as “Christian”.

Yes, though, they are equally, if not more, brainwashed in their beliefs of “the Prophet” & Islam. Both of which have continued to be portrayed in positive light, by moslems & their clerics in the West & East. And, we in the west keep facilitating & supporting them.
The rest of your post I completely agree with
