Terrorism, in its broadest sense, is the use of intentional violence and fear to achieve political or ideological aims. The term is used in this regard primarily to refer to intentional violence during peacetime or in the context of war against non-combatants (mostly civilians and neutral military personnel)

Sure seems to fit the wiki description at least

“Kurdish intelligence believes that over 40,000 civilians have been killed as a result of massive firepower used against them, especially by the federal police, air strikes and Isis itself,” Mr Zebari added. Mr Zebari, a native of Mosul and top Kurdish official who has served as the Iraqi finance minister and prior to that foreign minister, emphasised in an exclusive interview that the unrelenting artillery bombardment by units of the Iraqi federal police, in practice a heavily armed military unit, had caused immense destruction and loss of life in west Mosul.

40k dead in around 9 months, largely from bombing campaigns

Israel is at around 23k dead in around 4 months, not yet including the potential dead under all the rubble from the residential areas, hospitals, and schools being bombed. Also not including those who will die of dehydration, starvation, and disease due to Israel artificially restricting food, water, electricity, fuel, and humanitarian aid.

These are also two different situations. Do you think Israel is an apartheid state?
