This may be true but the actions of the Trump administration have many allies questioning how reliable the US is. That's not "stirring the pot" - it's potentially a significant shift in the world order and a decrease in how effective our foreign relations are.
The public allegations and concern expressed by our allies and own intelligence agencies should give everyone some concern regardless of one's political leanings.
As compared to the actions of the previous administrations, like bombing in eastern Europe, invading several countries, and royally fucking up Middle East etc, while constantly pushing Russia in the corner in cold war like rhetoric (for doing 1/10 of what they did, and in its actual bordering countries after) all in the span of 20 years?
It's been widely reported that allies are increasingly military spending and reassessing defense strategies after comments/actions by Trump.
That's because they have been in bed with US interests (as countries, not necessarily as populations) since the Cold War.
Thankfully the real decision makers aren't going to toss away decades of political good-will and foreign relations because of 3 weeks of blowhard political posturing.
Trump has been making it clear for a long time that he doesn't care about following the rules. He may not have a firm grip on reality, but he's consistently prioritized short-term interests of his view of America over long-term global stability.
