In case there are leftists reading:

Islam forbids allying with non-muslims:

Quran 5:57

O you who have believed, take not those who have taken your religion in ridicule and amusement among the ones who were given the Scripture before you nor the disbelievers as allies. And fear Allah, if you should [truly] be believers.

and commands jihad against ... well everyone:

Quran 9:73

O Prophet, fight against the disbelievers and the hypocrites and be harsh upon them. And their refuge is Hell, and wretched is the destination.
