About Y haplogroups O and D in western Europe？

[中国韭菜]

I know there are few western European men of Y haplogroup O，but it seems no D has been found among western Europeans by me.So how many western European men have O or D as their Y haplogroups？And how did they have O or D ancestry？

Asian Haplogroups in Europe is most likely reduced to 2 options.
The first is, they came during the Bronze Age Migrations from the Steppe.
Or, they came from the Huns, a Siberian/Mongoloid nomad people that arrived in Europe during the chaos of the late Roman Empire and the Barbarian invasions.
The Huns however, where a very short lived empire with little long lasting impact, much like the Mongols.
