Ukraine is losing its war against Russia. Here's what its defeat might look like.

• Ukraine is on the ropes amid a $60 billion US aid block. 
• Its leaders are issuing increasingly stark warnings that it faces defeat. 
• Defeat could take many forms, including the loss of key territories. 

With a $60 billion US aid bill blocked, Ukraine's battle against the Russian invasion is becoming increasingly desperate.

Its military is running critically short of artillery and ammunition, and it is being outgunned 10 to one is some places as it struggles to hold off intensifying Russian attacks.
