Britain and Germany are set to pledge new air defense systems for Ukraine as the UK government pushes for a “50-day drive” to arm Kyiv and bring Russian President Vladimir Putin to the negotiating table.

Trump has grown increasingly critical of Russian leader Vladimir Putin as a ceasefire in the war has not been worked out and Russia continues to bomb Ukraine.

Putin’s refusal to compromise on Ukraine, say analysts, is a colossal error costing Russia regional influence, lucrative energy markets and its place in the world.

Donald Trump has already threatened to impose “very severe” tariffs on Russia if it does not agree to a ceasefire by 2 September, 50 days on from the US president’s announcement that he would sell “top-of-the-line” weapons to Nato that could then be given to Ukraine.

Peskov also addressed recent comments by US President Donald Trump, noting that the world has grown accustomed to his sometimes “harsh” rhetoric.

Former Secretary of State Condoleezza Rice said she believes “this last week was a turning point” in the U.S. and European stance toward Ukraine and Russia.

Ukraine’s president proposed reviving talks brokered by the Trump administration, which seemed stalled a month ago.

US President Donald Trump’s 50-day pause ahead of possible secondary sanctions on Russia gifts the Kremlin a window to exploit the incremental gains of recent weeks in Ukraine’s east.

Sitting in the Oval Office with NATO Secretary-General Mark Rutte, and apparently fed up with being slow-walked by Russian President Vladimir Putin, Trump threatened the Kremlin with tough tariffs if it doesn't make a deal to end the war within 50 days. But perhaps more important was Trump's shift on weapons.

A face-to-face meeting between the Ukrainian and Russian leaders is needed "to truly ensure a lasting peace," Zelensky said late on Saturday.
