I think you need to get your facts straight. All of your examples were triggered by internal forces - not by the US or its allies.

The Syrian conflict was triggered by a protest that quickly escalated into civil war.

US and Allied forces supported the Northern Alliance in Afghanistan after the Taliban controlled government stated it was going to protect Al Qaeda following 9/11. 9/11 was a clear act of war in which Canada and other NATO countries are obligated to support.

Again, the democratically elected Egyptian government of the Muslim Brotherhood was overthrown by a military coup after it became clear the new government wanted to impose Islamic law. The US, as were other nations were concerned about the new military government and used their influence to ensure new elections were held. Not ideal - but better than the alternative and certainly not instigated by the US.

The US and other allies (including Russia) reluctantly supported the rebellion started in Libya.
