Question about Boris Johnson, Ukraine and his security [View all]

I am no Boris Johnson fan, but he is the Prime Minister of the UK, one of the most powerful people in the world. He is walking through Kyiv with a pretty minimal security presence, with Volodymyr Zelenskyy, the President of Ukraine.

Is anyone else a tad surprised to see this ? My guess is that President Biden could never do this because of the *probable* Russian desire to assassinate him. Biden had to make his speech in Warsaw, many miles from the border.

Thanks in advance.
