Nationalism puts the country’s interests above all. Islamic unity puts Islam above all. Therefore they cannot coexist. Just because someone is a Muslim doesn’t mean he cares about your country, your people, your history, your culture. Remember Daesh and when our very own HAMAS joined them? What happened to Muslim unity then? It’s all Muslim unity until they no longer need you or see another opportunity. Do you really think any of our “allies” care about Iranian lives? Do you think they care about you or your family in Tehran?
