Apologists for Islamic Jihad say that jihad is only "defensive". But defensive includes fighting those who simply oppose the spread of Islam or Islamism.
Sheik Ahmad Abu Quddum makes it crystal clear:
This fighting is in order to remove obstacles. It is waged against countries, not against individuals. When we declare Jihad against Germany, for instance, it is declared against the German state, for refusing to allow Islam to spread to the people of Germany. We give them a choice: Either to convert to Islam, or to pay the jizya and submit to the laws of Islam. The jizya is the only tax paid by non-Muslims, whereas the Muslims pay the zakkat, the kharraj, and the rikkaz, as well as other taxes, if there is not enough money for the army…
This is bog-standard Islamic doctrine and ideology.
