The EU 28, as I've explained many times before on this forum, generally reach agreement on policy and regulation by common consent, without the need to take matters to a vote in Parliament, though that option is there. The power of veto is there at various agreed levels, typically according to the size of the state that might invoke it, but more commonly the veto will be considered not by an individual state but by a bloc of states. The UK is regarded as one of the more argumentative states of the EU, but even so we have accepted without demur 95% of all proposals (thousands of them) and have only disagreed with any vehemence on half of the rest. In contrast, the UN has several massive states with individual powers of veto that are used for purely ideological reasons. For example, the US exercises its veto utterly routinely in order to prevent any criticism whatsoever of Israel, regardless of the level of atrocity carried out by that country's regime. Consensus is not possible under those circumstances. Your support of the UN over the EU is completely arse about face.
