And going to war with Iran is not conservative....especially when Trump lied to your simpleton MAGA ass and said he would start no new wars.
That depends upon insight into the reasoning for going to war with Iran, one's perspective of the last 5 decades and of the Obama deal with Iran.
Also, Iran isn't a "new war". Over the last decades, they've made their intent clear and have killed hundreds of US citizens, in addition to being the destabilizing factor in the ME and largest sponsor of terrorism. And they've made it very clear what their intent is for America (and Israel).
There are more valid reasons for dealing with Iran now than not. All admins (and indeed the world) have opined that Iran should be dealt with since Reagan. The real problem for the Left is the POTUS who is dealing with it.
If Trump pulls this off, the reality is that he will be historically hailed for one of the most consequential presidencies in recent history. The Left hates that.
