Why is there not a single UCITS ETF in the defense sector with European only companies?

Le posteur recherche un ETF UCITS composé uniquement de sociétés européennes du secteur de la défense, mais n'en trouve pas.

Im trying to find an accumulation ETF that only has defense stocks from European companies and not a single one in UCITS format. There's EUAD but it's not UCITS, I think this is ridiculous. Europeans cannot quickly support their own defense with a basket of stocks.
