This line of thinking (a common one, invented by the Zionists who clamour for balkanisation of Iran and spread by the Saudi-funded propaganda networks) does not really stand up to scrutiny.if Iranian funds were not misappropriated in overseas advantures of these cave men.
Iran's total military budget is c. $6.8 billion (2022). This is less than half of Qatar ($15.4 billion) and a quarter of even tiny UAE's military budget ($27 billion!). Also significantly less than Israel ($23.4 billion), Saudi Arabia ($75 billion), Turkey ($10.6 billion) and Pakistan ($10.3 billion).
So the idea that the IR is wasting Iranian funds on 'foreign adventures' is simply not true. If anything, the reverse is true: the IR should be allocating much more funds to the military budget. Obviously Zionists dislike Iran extending its influence across the region because this is not in their interests, but it definitely is in Iran's interests, especially when it can be achieved so cheaply. Consider how much Turkey, Saudi and UAE have been spending in recent years to spread their influence across the region, then compare their results vs costs and I think that result will be very favourable to Iran's foreign policy.
Easy example to prove this: arming of Hezbollah with thousands of rockets/missiles led Israel to allocate billions of $ to prepare for that threat. That is billions of $ that might otherwise have been spent on their plans to attack Iran (which are public, extensive and constantly updated).
The only thing we can say for sure is that these events would be getting a lot more attention if they were in IranSo......russian,chinese or possibly iranian enemy action?.....or just old infrastructure and good old human incompetence to blame?
