Yes but they would have to have done specific genetic marker isolation work between the Arabs and the mongrelized jewish ashkenazim, the more closely related sephardim, and the eastern mizrahim jews to not bungle their batch so to say. Then they would have to figure out some kind of compound that targets specifically Arab genes. Then they would have to figure out a way to weaponize it efficiently without causing damage to any jew who may be nearby. Dispersed aerosol bombs with a biological compound that has a direct rate of transdermal absorption, and if they load up their batch with DMSO or similar carrier, it could work rather effectively, but there is a problem in your friends theory, multiple actually. The idea of using biological weapons targeting specific genetic markers in one demographic is fundamentally flawed due to the high degree of genetic overlap and historical mixing between various populations, especially in the Middle East
The Arabs are not a pure race. They are the result of original nomadic raiders raping captives (usually White women) and then generation upon generation of a mixed-progeny adopting a creed (mixing disparate races is the right skew of the bell curve of unhealthy breeding) therefore it is no coincidence why Islam is so backwards in a majority of its adherents. This is compounded by present-day inbreeding (left skew of the bell curve of unhealthy breeding) that makes it such a problematic variable to have in a society that is not full of these people.
Is Islam a threat to jews? Not historically. It has been their golem for many cases against advanced civilizations. They greatly weakened Aryan Persia with it, which then allowed the Mongols to further destroy it later. They let them in to Spain (Gates of Toledo) and that changed much of the makeup of the country and caused the Marranos to be problems later on. You are witnessing Islam's golem days coming to a close, like some rich racehorse owner discussing how to best euthanize his star horse because it is old and lame. Islam has served its purposes, and its time to go. They will keep the really retarded versions of it alive in foreign lands just to keep disrupting Whitey and to counter weakened and jewified Christianity.
Then the issue is that how can they isolate one genetic marker to attack when it is so muted from centuries of mongrelization? The jew is so mongrelized himself that they may mistakenly kill themselves by coming up with a biological compound in this manner. I don't think it can be done. Part of genetics is a mystery, a holy mystery, and that is why they have not "cracked" the human genome completely by their manmade mapping sequences. Many eugenicists were actually more mongrelized and jewish themselves in the 19th century, as if they were searching for a cure for their own madness rather than to aim for a better purer society. You see the same vein of eugenicist Darwinian chutzpah coming out of their mouths today when they rally to protect their condos and shopping malls in Palestine from the natives.
Most traits including susceptibility to diseases or certain genetic markers are polygenic, meaning they are influenced by multiple genes. Trying to isolate and target specific genetic traits across a population would require an impossible level of precision, especially given the genetic complexity within the populations (Mizrahi and Arabs are closest).
Then you run into a whole additional set of problems with the virus / germ theory. From what we have seen with the coronahoax, there was no magical killer flu, there were maledict shriners, jews, and freemasons who were killing people intentionally with the remdesivir protocol, then driving everyone else insane with fear propaganda from a complicit media, then the deaths started to skyrocket once the injections came out. It's the other way around, there are no contagious germs, especially ones that can target specific people, as I often thought the jews would concoct a sickle-cell plague once they got rid of Whites since the blacks were no longer needed, but then I realized this was folly too. The only thing dangerous is literal poison (heavy metals, carcinogens, free radicals, venom, neurotoxins) and the occult combination of MRNA and nanotechnology.
Remember these jews will lie to your face even if you're a "family friend," let alone a stranger they meet on vacation. What we have here is a lie within a lie. They lie about genetics, they lie about epidemiology, and they wrap them together neatly in a lie sandwich.
