Ok well all you are doing is limiting your ability to understand the real world. If you don't mind being ignorant then go ahead.
"God is the Greatest Death to America Death to Israel A Curse Upon the Jews Victory to Islam"
Is indeed a cartoon baddie.
(And I'm talking about the leadership, not just random followers)
For one thing, translating the words alone leads to a significant stripping of context. Additionally, movements around political Islam have only gained sway since secular/nationalist movements failed to achieve their goals in a meaningful way.
Yemen has more or less zero reason to be in direct conflict with Israel, it's as cartoonish as papa new guinea suddenly changing their slogan to "death to Cyprus!".
