No, Ukraine joining goes back at least to 2008 and George W. Bush's overconfidence. Russian aggression started in 2014.

Note that Georgia joining was also on the table. Several months after this summit Russia trounced Georgia in a few days and since then there has been no serious movement towards joining NATO.

Russia likely expected the same outcome in Ukraine but as we know now that didn't materialize.
