Trump's posture toward Vladimir Putin

In this week’s Q&A, Christiane and Jamie examine what the Iran war could mean for the Republican primary - and for two of its most prominent voices on foreign policy, Marco Rubio and JD Vance.

They discuss the contradictions in Trump’s strategy, including the easing of sanctions on Russian and Iranian oil, and ask why Vladimir Putin appears to be benefiting while the US is drawn deeper into war.

Plus they explore whether Trump has badly damaged America’s closest alliances, why countries like the UK and Australia are refusing to follow Washington’s lead, and what that says about US power, diplomacy and miscalculation.
