Best diversified ETF

Hello,

what is best diversified ETF to cover whole world and also has good returns? I am currently buying iShares Core MSCI World UCITS ETF USD (IWDA). But given the current political developments, does it make sense to switch to something else? Maybe something that is in EUR, or something where there is a larger share of EU shares than in IWDA? Or should I just continue in IWDA and ignore current events in world?
