Ukraine's prime minister Denys Shmyhal has told the BBC there will be a "Third World War" if Ukraine loses its conflict with Russia, as he urged the US Congress to pass a long-stalled foreign aid bill.

Opposition from the right wing of the Republican party has blocked potential assistance to Ukraine for months.

This is not the first time Ukraine has issued such an alarming warning about the consequences of its potential defeat.

Last year, President Volodymyr Zelensky said that if Russia won the conflict, it could next invade Poland, triggering World War Three.

While western leaders have also used the 'if Ukraine doesn't defeat Russia they will attack Europe' claim, that has purely been in support of NATO war-mongering and expansion eastwards. They know it's bullshit propaganda.

Even if it did seem credible at times, after two years of failing to take Ukraine, it no longer is.
