Iran is attacking Israel, in particular, with the Shaheds. These kamikaze drones are supplied by Tehran to Russia for the war against Ukraine. When a state is at war, it has fewer opportunities to supply weapons to its allies.
How an attack against Israel will affect cooperation between Iran and Russia
Over time, the supply of "Shahed" to Russia may be reduced or completely limited.
However, it is too early to conclude when this will happen and if it will happen at all. A military observer suggested that after Russia massively supplied kamikaze drones, Iran could use stockpiles because it would be tough to resume production so quickly.
Was it profitable for Iran to supply Shaheds?
David Sharp noted that Iran was profitable in supplying Shaheds to Russia for specific reasons. First, Iran was under sanctions, so it had a massive shortage of currency and technology.
Also, it was a test of these drones. "Shahed" has been used before in various countries, but not in such a quantity as Russia is doing against Ukraine.
