Ukrainian President Volodymyr Zelenskyy told ABC This Week co-anchor Martha Raddatz that he sees Donald Trump as a key figure who can end the war between his nation and Vladimir Putin's Russia.

In an interview that aired Sunday, the Ukrainian President noted that 'the majority of wars were finished with some kinds of agreements … [with] strong third parties involved who can put pressure on the aggressor,' Zelenskyy told Raddatz.

'Are there enough levers and powers to stop this in the United States? Yes, I am convinced that the president of the United States has all the powers and enough leverage to step up,' Zelenskyy continued.

'He can unite around him other partners like European leaders,' he concluded. 'They [are] all looking at the President Trump as a leader of the free world, a free, democratic world, and they are waiting for him,' Zelenskyy added.

The Ukrainian President also called for America to pressure Russia via economic sanctions, noting that only the United States can actually make a difference.
