What is the significant shift in US policy towards Russia as revealed in the recent US-Russia negotiations?

The negotiations represent a complete reversal of US policy towards Russia. Instead of viewing each other as foes, the US and Russia now want to work closer together diplomatically and economically. Secretary of State Marco Rubio and National Security Adviser Mike Waltz emphasized the urgency of reaching a quick resolution to the Ukraine conflict, planning to arrange a meeting between President Trump and Vladimir Putin quickly. They stressed the importance of achieving a permanent peace that won't lead to further violence. This collaborative approach marks a stark contrast to Washington's stance in recent years.
