Nordic Flags and Other Symbols

I knew the "Flag of Portland" is a fusion between Nordic flags and a swastika Portland Trail Blazers logo is a ying-yang.

Trimet logo is inciting to... try meth and also the middle part of a Darmachakra?

But i never realized NATO (North Atlantic Treaty Organization) logo has a swastika embedded in it.

And definitely never saw this variant that has Hitler's Zoroastrian wings on it. Is the triple flame on top what i think it is?

In a way it makes sense, both swastika and NATO logo seem to have been taken from the Ninja (noongars) arsenal of missiles and at origin they could have been boomerangs
