From Luke Coffey's article For Eastern Europe, Moscow is an existential threat, published by Al Jazeera:
"Russia's myths
There is a common misconception that the 1997 NATO-Russia Founding Act prohibits the permanent basing of NATO soldiers in central and eastern European countries. Russia regularly perpetuates this myth. This is not true.
In regards to the question of permanent bases the Act states:
During this same period, Russia has also conducted cyberattacks against NATO allies, invaded Georgia (and is still occupying 20 percent of that country), used energy resources as a weapon against its neighbours, and most recently, annexed Crimea and invaded eastern Ukraine.
Consequently, the "current and foreseeable security environment" has changed since 1997. Therefore, NATO is able to rightfully create permanent bases in its Eastern European member states."

In regards to the question of permanent bases the Act states:
NATO reiterates that in the current and foreseeable security environment, the Alliance will carry out its collective defence and other missions by ensuring the necessary interoperability, integration, and capability for reinforcement rather than by additional permanent stationing of substantial combat forces.Since this agreement was signed in 1997, Russia has failed to remove troops from Moldova as promised and increased troops in Ukraine, Armenia, and Belarus - all of which border NATO.
