Israel has expressed dissatisfaction with Russia's supply of advanced military components to Iran.

The claim that "Israel has expressed dissatisfaction with Russia's supply of advanced military components to Iran" is supported by the context of ongoing military cooperation between Iran and Russia, which has raised concerns for Israel. Various sources indicate that Russia has been involved in military and technical cooperation with Iran, including the supply of advanced military components. However, the specific expression of dissatisfaction from Israel regarding these supplies is not explicitly detailed in the available sources. While it is widely recognized that Israel views Iranian military advancements with apprehension, particularly in the context of regional security, the sources do not provide direct quotes or statements from Israeli officials expressing dissatisfaction specifically about Russian supplies to Iran. Therefore, while the underlying premise of the claim aligns with the broader geopolitical context, the lack of direct evidence of Israel's dissatisfaction limits the claim's strength.
