Israel is a country
Israel is not a country, it is an occupying force that has been carrying out genocide in Palestine for decades. Zionists are also followers of a dangerous cult that thinks their "race" is the superior race and everyone else is "animals" needing to be put down or enslaved.
There is an Iranian expansionist project at the expense of the countries of the region, so we find it supporting any Shiite group and also providing them with weapons and money.
Again that's what the propaganda wants you to believe. Iran is a Shia Muslim country but majority of the people Iran supports are not. The most obvious ones are the Palestinians who are Sunni Muslims, Jews and Christians.
Iran is the supporter of the oppressed regardless of their religion, nationality or race; and that is part of the Islamic Republic of Iran's constitution, and has been part of the Iranian culture and ideology for thousands of years. IRI has been the supporter of the oppressed Africans back in the time of Apartheid in South Africa all the way to the oppressed people in West Asia during the US-backed ISIS terrorism.
This is not a Islam related or Shia related thing either. This has been the Iranian way for thousands of years, even predating Islam itself.
For example nearly 2100 years ago when the Marcus Licinius Crassus was raiding villages and slaughtering unarmed people in places that are Turkey and Syria today, it was the Iranian commander Surena that went to help and crushed the Roman army that was committing genocide. That is 700 years before Islam.
Or when Nebuchadnezzar had enslaved Jews in Babylon, the Persians (Cyrus the Great) liberated them and that was 2600 years ago (1200 years before Islam).
Iranians have been helping the oppressed even at their weakest moments. Like during WW2 when the Allies attacked Iran and stole all the food causing mass starvation that led to death of nearly half the population; the Iranians still opened their borders and accepted refugees of the WW2 conflict with open arms. Specifically the Polish refugees.
That ideology is all over Iranian poetry as well. From 13th century:
بنی آدم اعضایِ یکدیگرند که در آفرینش ز یک گوهرند
چو عضوی به درد آورد روزگار دگر عضوها را نماند قرار
تو کز محنتِ دیگران بیغمی نشاید که نامت نهند آدمی
But of course when the enemies who want to continue committing genocide, the dictators who see their dictatorship threatened, etc. see the only thing that can stop their atrocities is Iran, they have to make Iranian help look "dirty".
That propaganda can't work forever though. This is why we saw in Operation True Promise 1 and 2, the dictatorships like Saudi get angry and start spreading the same propaganda in their media while the people of Arabia celebrated it as if it were their own victory.
