Given the political and economic situation in Czech Republic right now, it is completely understandable. We have in the region of 400,000 Ukrainian refugees here, in a country with a total population of around 10.5 million, inflation currently running at 17%, and a population split between those looking west and a fair number who support authoritarian parties and look to Putin as an example (see my post in the other thread about the pro-Putin protest in Prague a couple of weeks ago).
The wording is shit, but that's not unusual for Czech politicians. It's not about toadying up to Russia or fear of invasion. The current government - a broadly centre-right, west-looking coalition - is absolutely against Russia.
