Some of the things Lewis has said about that subject:
“I never read the papers. Why does anyone? They’re nearly all lies…” (Letter of 10/26/55 to Mary Shelburne)
“…the content of the newspapers…is possibly the most phantasmal of all histories, a story written not by the hand of God but by foreign offices, demagogues, and reporters.” (Christian Reflections: 9, 26 – “Historicism”)
“To read without military knowledge or good maps accounts of fighting which were distorted before they reached the Divisional general and further distorted before they left him and then “written up” out of all recognition by journalists, to strive to master what will be contradicted the next day…is surely an ill use of the mind.”(Surprised By Joy, chapter X).
And now, the relevance of this to the present situation in Ukraine:
The mainstream media and Western governments shout that the Russian invasion of Ukraine is “unprovoked”. This is not the case. The first provocation came in 1998, when NATO decided to expand its borders to the east to countries bordering on Russia, without any provocation by Russia. George Kennan, former ambassador to the USSR, warned that this would end in catastrophe, as it has.
The second provocation came in 2014, when a coup overthrew a democratically elected president who was going to side economically with Russia rather than the European Union. One of the immediate results of this coup was eliminating Russian from its status as an official language of the country. The coup also created a threat to the Russian Black Sea Fleet in Crimea, and brought about the annexation of Crimea, to the applause of most of its citizens. But when the mostly Russian population of Eastern Ukraine saw their status as Russians become diminished, and how easily Crimea once again became a part of Russia (which it had been until Khrushchev “gifted” it to Ukraine in 1956), they, too, wanted to have the same privilege, and began a civil war, which has resulted in about 14,000 deaths in that part of the country by now. In 2015, an agreement (The Minsk Accords) was worked out between the governments of Ukraine and Russia, with France and Germany as the intermediaries, which would have given more autonomy to eastern Ukraine. Unfortunately, the Minsk agreement was never ratified by the Ukrainian parliament, and the war continued, leaving the people of eastern Ukraine almost totally abandoned economically, both from Ukraine, and receiving very little support from Russia as well, because Putin was reluctant to incur even greater wrath from the West, although, morally, it would have been the right thing to do.
When about a week ago, Russia formally recognized the eastern break-away republics, I thought that, morally, it was the right thing to do. But it seems that the Russian military (according to Putin) thought that this would only result in more arms being brought in from the West into Ukraine, and a full-scale invasion was launched, in order to settle things once and for all. How all this will end is a good question.
