Address of Oleg Chertov, Head of the Applied Mathematics Department, in the Slack messenger to the students of the department (it was February 28):
"Dear colleagues, congratulations!
No one believed - neither the American secret services, nor the British, much less - the Russian ones.
But we persevered, although Rusna is like a locust.
Quotes from current posts:
"DIGs wear our uniforms. The only way to identify them is in Ukrainian. Speak to the military you meet only in Ukrainian!"
"The Ukrainian military speaks exclusively Ukrainian (not even perfect) to distinguish and identify the enemy!"
I hope that some of our colleagues, though now, will understand why I responded in Georgian or Chinese to their message in Russian.
There are no trifles in these issues.
And for some mistakes, unfortunately, you can only pay with blood. "

And today the President of Ukraine announced that Ukraine will introduce a visa regime for Russian citizens from July 1.
It is good that no one wants to look for something in putin's eyes.
