It is very clear cut. All Eastern European countries support Ukraine. In Czechia (and I believe in Slovakia) there are some groups convinced that if their countries stop support Ukraine, somehow miraculously peace will manifest. Moreover, millions of Ukrainians fled the war - it's a miracle there weren't any mass backlashes or provocations yet given the number of people that relocated and lives on foreign soil. But Ukraine has enormous support in the whole East Europe because these folks know they're next in line - they can even hear such threats from Russian TV and some politicians.
