Ukraine although not in nato, had been doing training with nato for a while prior to the invasion.
This argument is essentially denying Ukraine's right to sovereignty. It's a bad and disingenous justification for a wholly illegal and unprovoked invasion of a sovereign country.
How high do you let the gun get before you consider it provocation?
The invasion happened after the unofficial joining of nato, obviously.
Do you really think there is a country that would not react if a very big neighbouring country were to join an enemy military alliance?
The first was in 2008 when NATO decided Ukraine could start the NATO membership process.
This came to a head at the start of 2014 when Euromaidan revolution lead to a change of government.
In 2014, the Ukrainian parliament renounced Ukraine's non-aligned status.
In 2016, Ukraine was granted a NATO Comprehensive Assistance Package (CAP), comprising the advisory mission at the NATO Representation to Ukraine as well as 16 capacity-building programs and Trust Funds.
In 2018, Ukraine was officially given an aspiring member status.
2021 NATO reaffirmed that Ukraine will become a member.

That is laughable. They annexed Crimea in 2014, and now claim Donetsk, Kherson, Luhansk, and Zaporizhzhia. Very strange behavior for a country that is just 'protecting itself from NATO'.
Russia's problems are all of their own making. They had no need to invade Ukraine. They did so because Ukraine didn't want to be their puppet state like Belarus. The Russian government wants to treat former SSRs like they're still economic tributaries to Moscow.
