I don't see the first being an issue; If it's in their territorial boundaries. I think they need not to be caught off-guard like Ukraine. Poland was an important Soviet boundary, and it would _seem_ Putin's primary motivation is geopolitics and restoration of Soviet-era boundaries... (I have trouble believing that statement but it's the only explanation that makes any sense for current events).
The second... probably risks escalation and I think your point is valid.
