Well, in my defence, i was replying to a poster with very right wing entrenched views.....
But i'll address your points:
No i don't blame the Tories for everything, though tbf i cannot really think of anything good they ve done either.
Both parties cut defence but it was the Tories who were in power when Russia took Crimea and then tried again in Ukraine, they never increased defence spend even after these actions.
Blair never fixed Social Care, never built Council housing, never fixed dentistry, roads never invested in.... all though made worse after 2010 and Austerity.
Uncontrolled Immigration under Blair did take place but it was almost all from Europe, didn't bring all their dependents, easy to integrate & many have returned, though we don't know how many as we don't record this but given eastern european booming economies, a great deal have.
The Tories, after 2020, allowed in many more times the numbers Blair did but from SE Asia, Africa, all bought dependents, zero chance they'll go home
I don't agree we are un governable, we have certainly decided that many crimes are no longer treated as such, thats true but the reasons for much of our decline, imho, is the lack of public services, we are all paying for services that are so poor, they might as well not exist.
I can't comment on what system of Govt Blair helped introduce, i'm not aware he did such a thing.
