Hezbollah's founders writings at the time are available online, and that they are clear about their goal being the rule of Islam. Their slogan was 'The Islamic Revolution in Lebanon'. They were founded as an Islamic revolutionary group, that is very core to who they are. Highlighting that is hardly 'using Islam as a scapegoat' whatever that means.

You are trying to obfuscate Hezbollah's public statements calling for Islamic rule. Hezbollah wants Islamic rule and Sharia law for Lebanon, they are very clear about this. Currently realities that they have to put up with do not change that. They are also clear all of their actions and philosophy is consistent with and based on Islamic teaching. Again it is not deceptive to point out they are an Islamic organization.
