Britain's Ben Wallace, A Contender To Run NATO, Details His Vision - The Washington Post
I'd support that, I think he'd make a good NATO Secretary General, UK was the first to send Western MBTs, the first to send Long-Range Missiles and IIRC the first to send Anti-Ship Missiles. Amongst the first to supply Ukraine and one of the heaviest suppliers.
I think Kaja Kallas would be better as European Commission President but her no nonsense attitude towards Russia would make her a good NATO Secretary General too, if Jens decides to leave, Jens has been good though so ideally I'd want him to stay until Ukraine wins.
