Donald Trump must use all means to get Putin to accept the unconditional 30-day ceasefire.
Russia avoided committing to the ceasefire proposed by Ukraine and European allies.
Russia's low-level representatives insisted Ukraine must renounce the invaded provinces before a ceasefire.
Putin continued with the bombings despite peace talks.
Trump's negotiation attempts have been flawed and focused on his own business interests.
Severe sanctions should be implemented on Russia's oil and banking sectors.
A resolution for peace would be worse if Trump withdraws and leaves the responsibility to the Europeans.
Conclusion: If Trump does not act and impose pressure on Putin, the responsibility of the war will fall on him, damaging the international credibility of the United States.
