There's no power in this world that can erase Arab-Persian race wars. It is something ingrained in the matrix.
Do you honestly think that the second largest ethnic group in the world (Arabs) numbering close to 600 million people (if one of the largest diasporas in the world - the Arab diaspora is included), only second to the Han Chinese, inhabiting a landmass the size of Russia and stretching from the Atlantic Ocean to the Arabian Sea/Indian Ocean (well over 10.000 km in distance), obsess about "Persians" (which are barely the majority in Iran to begin with) at all let alone some imaginary "race war"?
Let alone know much or anything about them when 90% of all Arabs live far away from small (tiny in fact in comparison) Iran?
Take a look at that map and compare it with the size of Iran.
We think about the US 1 billion times more in comparison because they are an actual world power whose economy, politics, global cultural influence in terms of entertainment, science, military cooperation etc. matters.
The only reason why Arabs not far from Iran even think about it, is due to their opportunistic meddling in war torn Arab nations since 1979 - luckily something that is soon going to collapse completely. Which is the work of their regime (ironically run by self-proclaimed Iranian Arabs (Sayyids) and more obsessed about Arab affairs than the two only other "Iranic" nations in the world in small landlocked Tajikistan (one of the poorest nations on earth) and Afghanistan (same thing).
Other than that Arabs have influenced Iran and Persians tremendously, religiously, culturally, linguistically, ethnically and most other aspects. To the degree that Arabia has historically, even to this day, been a safe heaven and place for economic refugees from Iran (Persians included) and religious ones (Sunni Persians). Hosting the largest Iranian diaspora in the region by far.
Strange that those same Iranians (ordinary people not obsessed about Arabs) have not preferred living in Turkmenistan, Afghanistan, Pakistan, Azerbaijan etc. next door instead or even Iraq.
It is for those very reasons that most South Iranians (Persian heartland - go take a look at a map - Fars province is closer to Eastern KSA/East Arabia than much of Iran itself) and Arabians (Eastern Arabians in particular and Iraqis) have had overall cordial people to people ties.

That is besides mentioning the fact that there are millions of Iranian Arabs who we have historical ties to much like Arabs in actual Arab-majority inhabited countries.
Another thing altogether:
Anyway this thread has nothing to do with Iran or anybody else for that matter. It is merely an accident and it has nothing to do with the military unless Saudi Aramco employees (regular petroleum, chemical and other engineers) are now part of some imaginary military force.
So in short, most sane Arabs do not obsess or think much (if anything) about "Persians" and have nothing against them or the opposite. Which the actual ground realities confirm. Not some imaginary "race wars" or online nonsense that non-Arabs often obsess about from my interactions throughout the years confirm more often than not.
Unfortunately quite a few "Persians" (in particular those against Islam etc.) seem to obsess about Arabs (despite largely being completely clueless in terms of everthing even remotely related to "Arabs") and blame all their miseries on "Arabs" but that is their problem, not ours.
Lastly this thread, not sure what the point of it is on this section as this is purely a military section and this accident has nothing to do with military affairs.
