Finnish President Alexander Stubb discusses the current geopolitical situation following Ukrainian President Volodymyr Zelenskiy's visit to the White House last week. He also talks about Russia and how President Vladimir Putin won't stop with Ukraine if he's not countered with strength in any negotiations over a ceasefire or peace. He spoke with Bloomberg's Francine Lacqua in London as he joined other European leaders to discuss the situation in Ukraine and security guarantees.
