London is hosting crucial talks this week that could decide the future of the Ukraine war. Ukraine’s defense minister is largely in agreement with a ceasefire plan proposed by former US President Donald Trump. This plan, which was introduced in Paris, is said to be about 90% acceptable to Ukraine. However, there are concerns over territorial issues in the ceasefire deal. The U.S. aims to finalize a comprehensive ceasefire and is prepared to engage with Russia to see if a deal can be reached. If Russia rejects the plan, Europe may have to take on more responsibility for security.
