Paris - Russian President Vladimir Putin stagnated on the peace dining table while preparing for a new military offensive in Ukraine, two U.S. senators warned on Sunday that the next two weeks could impact a war that had already smashed cities, displaced cities, displaced cities, and redefine Europe's security map.

Republican Senator Lindsey Graham and Democratic Senator Richard Blumenthal were damaged by the worst Russian bombing after meeting with President Volodymyr Zelenskyy and the Circuit Community.

Talks with French President Emmanuel Macron in Paris, who said they were "100% consistent" with them in the war - the senator warned that the window prevented reattacks. They say a thorough U.S. sanctions bill could be the last chance the West will stifle the Kremlin war economy.

"What I learned on this trip is that he is preparing for more wars," Graham said of Putin. Blumenthal called the sanctions proposed in the legislation "fragmented" and said it would put Russia's economy "on the trade island."

"This is austerity time for Putin and the world, as Russia is taking a new offensive," he said.

Their push is a bipartisan sanctions bill, supported by the entire U.S. Senate, but still faces uncertain odds in Washington. It will impose 500% tariffs on countries that continue to buy Russian oil, gas, uranium and other exports - targeting countries such as China and India, accounting for about 70% of Russia's energy trade and accounting for most of its war efforts.

Graham called it "the toughest bill I've ever seen in my life in the Senate."

"There are a lot of cards in the world with Putin," he said. "We will attack China and India to support his war machine."

Peace negotiations are scheduled to resume in Istanbul on Monday. But Ukrainian officials say Moscow has not yet made a serious proposal - delaying the senator is described as intentional and dangerous.

"Putin is playing President Trump," Blumenthal said. "He is taking him to attract people." The senator said Putin was "actually stagnant and the stone wall, extending the conversation so that he could carry out this offensive and control more territory on the ground."

Graham added: "We see solid evidence of the summer or early autumn invasion, which is Putin's new offensive. ... He is preparing for more wars."

Trump has not endorsed the sanctions bill, telling reporters Friday: "I don't know. I have to see it." Graham said the legislation was drafted in consultation with Trump's advisers.

Graham supported the president's diplomatic instinct, but said: "Trying to interact with Putin in a friendly and seductive way - it's clear that he's not interested in ending the war."

Blumenthal hopes that bipartisan support for Ukraine in at least the Senate — and personal testimony of their plans to bring Congress and the Oval Office home may help change the conversation.

"He also needs to see and hear this message from us, the American people," he said of Putin.

The senator said that in Kyiv, human losses from war were impossible to ignore. Graham noted that Ukrainian officials and Yale researchers estimate nearly 20,000 children who were forcibly deported to Russia - saying their returns are judicial issues, not diplomacy.

Blumenthal describes standing at the large grave site in Bucha, where civilians were shot. He said the destruction and the stories of those who survived clearly demonstrated the interests of delay. "Putin is a thug. He is the murderer."

Both sides say that not taking action now can lead to deeper conflict in the United States in the future. Blumenthal said that if Putin did not stop in Ukraine, the NATO treaty obligations could one day force the U.S. troops to join the battle.

After an hour-long meeting with Macron in Paris, Graham, South Carolina and Blumenthal, Connecticut, both said they left, confident that Europe was ready to stick to its position.

"This visit was a breakthrough moment as President Macron showed moral clarity in his conversation with us," Blumenthal said. "Today, he is 100% aligned with the message we are going back to Washington."

Blumenthal pointed to the bipartisan unity behind the sanctions bill. "There are few reasons why 41 Republicans and 41 Democrats are needed and documented in one legislation," he said. "The reason for Ukraine is doing this."

In the future, Ukrainian military leaders will briefly introduce the parliament and may subsequently conduct sanctions votes.

"President Trump said we will know in two weeks whether he was tied up," Graham said. "There will be more evidence on Monday to show Russia."
