Iran has loose relations with both which are not dissimilar to the one it has with the EU. Its conflict is also fairly limited to Israel and the Middle East.
Meanwhile, Russia and China have an ambivalent relationship where they are key economic partners with complementary economies but have no official military alliance and are somewhat wary of each other as Russia fears a potential Chinese invasion.
It's the other way around. Europe fueling war with china + russia + iran.
It isn't china sending warships along german, british, european coastline. It wasn't russia that overthrew democracy in ukraine. And it isn't iran bombing europe.
> They openly declare a war on way of living of western world .
No. You once again have it backwards. It's the western world declaring war on them. The genuine head scratcher is why china, russian and iran haven't formally joined forces to fight back.
