He has given himself an out. I guess he will never think it's the "right time".
Britain’s opposition leader Sir Keir Starmer said on Friday that he wants to recognise a Palestinian state if he wins the General Election in July, but only if such a move is at the right time as part of a peace process, Reuters has reported.
Sounds to me much like the US's constant "we support a two-state solution, but this is not the right time for that consideration."
It usually means they'll happily support Israel's demand that Palestinian statehood is refused, and take no actions against Israeli annexation of Palestinian land, but they
say they want peace and a two-state solution so they can blame Hamas, or any given Palestinian group for their actions against Palestinian statehood.
If Palestine are allowed statehood, they cannot be denied any right of defence to Israeli aggression. They cannot be denied re-entry to their own country, nor have their transport controlled by Israel. Any annexation of Palestinian lands would be acknowledged as illegal. Holding of Palestinian citizens without charge or trial would be an act against another nation's citizens. Essentially, Palestinian statehood would highlight many actions of Israel as illegal, and open up a right of response.
There's no way the countries that view Israel either as a colonial interest (the US and the UK, chiefly) or a useful excuse to avoid addressing antisemitism within their own borders are going to do more than lie about a hypothetical future where the conditions will be right for them to recognise Palestinian statehood.
