Europe ETFs

I have consolidated my portfolio to 3 etfs (majorly) 1) S&P 500 - IVV 2) ASX 200 - IOZ 3) India Nifty 50 - NDIA

I am contemplating if I should add europe etf for diversification purposes, something like IEU.

What are your thoughts? ( I am not that big of a fan of Europe stock market, so not sure if I should include that it in mg portfolio)
