How else can you wake the Russian populace to the evil their government does? To be honest with you, I think most should have figured it out by now.
The war will continue as long as Putin is in power. Losing the war means for Putin loss of power, as this has historically been the case in Russia:
Withdrawal from Afghanistan in 1989; two years later USSR dissolves and Gorbachov is out of power.
Backing down from Cuban Missle Crisis: two years later Khrushchev was removed from power.
The Korean War didn't end until Stalin died.
In 1917 the Russian Empire sued for peace to stop the fighting in WWI. Shortly thereafter the revolution breaks out and the Czar & family are shot.
So there is strong correlation between poor results in wartime and loss of political power for Russian leaders. Putin will only end the war on his terms.
For Russians to stop the war means removing Putin from power. The only way for this to happen is via a coup in the Kremlin.
A popular uprising won't achieve very much as Putin has control over all the levers of power. Besides, the Russian population is pretty apolitical at this point since the most politically attuned citizens have already left the country, so those remaining are not very likely to start protesting.
