In an interview with Le Figaro published on August 16 and based on his new book, former French President Nicolas Sarkozy laid out what has been missing from Western thinking on the war in Ukraine: a diplomatic Plan B in case the present Ukrainian offensive fails.

If it does fail, as seems increasingly probable, the most likely alternative to a diplomatic solution is an indefinite and bloody war of attrition along roughly the present battle lines.

Quite apart from the threats of disastrous escalation and a NATO-Russia war described by Sarkozy, Westerners who are or claim to be friends of Ukraine should consider the consequences of an unending war on that country. These include a continuation of dreadful human losses and continued destruction of the Ukrainian economy, with no certainty at all over who will pay to rebuild it. They would also entail the indefinite postponement of the process of EU accession, which would have offered Ukraine its best chance of truly joining the West and the inability of Ukrainian refugees to return home, leading to a catastrophic and permanent decline in Ukraine’s population.

In addition to all of this: the possibility that a Ukrainian army exhausted and bled white by years of failed offensives will eventually fall victim to a Russian counter-attack, leading to territorial losses far greater than Ukraine has suffered so far.
