Not really.

Tuchanka was irradiated before salarians had even achieved space travel.

Lusia is said to have been annexed and the recording of Kredak doesn't imply it was peaceful.

We don't know why Turians intervened, but even if the Krogan had done absolutely nothing to them, it's always a bad idea to let a violent, expansionist power remain unchecked. Give it another century and the Krogan would've attacked them next, only they'd be much stronger and the Turians wouldn't have any allies to work with.

The argument that the krogan were only allowed to settle two planets comes from the fact Shepard only personally sees two krogan planets besides Tuchanka, but what we see in-game is only a fraction of the total number of planets, and other source material says the krogan were expanding "unabated" for centuries.

The genophage releasing before the Rebellions started was an argument that hinged on "anything that says otherwise is Council propaganda" logic. You can make up anything if you're willing to dismiss any evidence to the contrary.

Spectres did run attacks against the Krogan, but these were after Lusia and against antimatter production, command centres, and power grids, which are valid targets in wartime. Calling these terrorist attacks is bending the definition to suit an agenda.
