He added that the West must continue its support for Ukraine to pile more pressure on Putin.
Mr Drummond said: "The West is at a crossroads. Some people are saying Putin has won and the war in Ukraine is done. But other people are saying it is far from done.
"The longer we keep this pressure up, eventually we will cause a collapse of Russia from within.
"If the West lets Putin succeed in Ukraine, we will send the worst possible message to China. They will think 'We can invade Taiwan, and no one can stop us.'"
According to Ukraine, Russia has suffered over 500,000 casualties during the war.
Mr Drummond believes Putin's strategy is bringing the war in Ukraine closer to Russians at home.

However, the sheer scale of the casualties he is taking means he will meet resistance internally due to burning the flower of Russian youth on the Ukrainian battlefield.
"It was reported recently that he lost 1,400 men in one day.
"There are pictures of these new graveyards in Russia. They are enormous, and they are really bringing the war home to Russians."
