Lebanon had a civil war along religious lines. There are many Lebanese Christians in the USA that could help you with what seems to be a misunderstanding about the country.

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.
