"This does feel like the way it was when and why we left in the 90s. Like my old PTSD I’ve finally fixed is coming back. I literally only just forgot about those ‘always on the edge’ feelings and actually started worrying about things like bbq grills. I’m crying as I’m typing this because all man deserves to worry about ‘bbq grills’ and not f---ing war.

"Conjuring" actress Vera Farmiga, who has Ukrainian roots, posted to Instagram the country's flag along with some lyrics from its national anthem. She used the hashtag #IStandWithUkraiine.

"Today my heart hurts because no matter how many great works of art and music (Guernica…. Masters Of War… Most of Okudzhava and Vysotsky… Vonnegut… Remarque… all those films in all those languages…) portray the horrors of war, new Masters of War seem to rise up again in all the nations… Sending new children to slaughter each other," wrote Spektor, 42, who was born in Moscow before her family left the former Soviet Union for New York City in 1989. 

"There were, and still are, real Nazis in the world. But in Ukraine that are just millions of civilians being pulled into a war, and in Russia there are children being sent to fight and die for no reason other than the bottomless and horror filled 'more more more more more more more' of politicians and corporations. And it's terrifying."

"It's honestly really hard for me because, yes, I do live in the United States now, but Ukraine, it is my home," Zaya said. "I love my country, and it's just so hard for me to even think that in 2022, in this world right now, war still exists, and people can kill other people for land and money."

Zaya said she's spoken over the phone with friends in Kyiv, who woke up to explosions early Thursday.

"My friends are calling me all the time. I just talked to my friend, and she's like, ‘Yara, I’m so scared. I'm hearing the bombs. I'm hearing the explosions. I don't want to hear the noise,'" she said.

Explosions sounded before dawn in Kyiv and gunfire was reported in several areas, as Western leaders scheduled an emergency meeting and Ukraine's president pleaded for international help to fend off an attack that could topple his democratically elected government, cause massive casualties and ripple out damage to the global economy.
