Trump invades Venezuela with ground troops

Yet radio silence from Kevin when a Democrat does the same.

When has a Democratic president ever invaded another country with whom the US was NOT at war and kidnapped its leader?

He never got beyond third grade. We know this because his English skills are well below what it takes to advance to fourth grade.

Dude failed at life.......don't get it twisted. 

These may not fit perfectly into what you've asked for as I do not know if the leader was kidnapped in all examples but......

1915 - Invasion and occupation of Haiti.

1916 - invasion and occupation of the Dominican Republic 

1950 - Korea

1950 - Vietnam 

1964 - Dominican Republic 

1993 - Somalia

Additionally several Presidents, some of them Democrats have invaded countries to protect "US business interests" I.e the banana wars and similar conflicts. 

Hawaii was occupied under Grover Cleveland in 1893. Although to his credit he didn't give the orders, recognized it was illegal and tried to reverse it.

Through the '90s and 2000s we did all sorts of Black ops against "drug producers" in south and central America. Often without Congressional approval. (Granted with these, we usually have the permission of the country's government, but we still lacked approval from Congress)

Do we need boots on the ground to count as an "invasion"? 

Bill Clinton lacked Congressional approval for many of the airstrikes and military campaigns he performed. 

Obama lacked Congressional approval for many of the airstrikes and military conflicts he performed. 

Unconstitutional wars/armed conflict have been waged from both sides of the aisle for a long time. 

Those actions were unlawful and unconstitutional, and they don't make Trump's present shit legal, lawful, or morally justified.

And yes, an invasion means one country physically invades another with armed forces. Not like Mexico "invading" the US with migrant farm workers, as MAGA luvvvvs to say. Military action without an actual invasion certainly has been performed by the US in the past against other countries. 

But in your list, I don't see a single instance of the US physically invading another country and abducting its leader. That's unprecedented.

I suspect that you share my disappoval of past and present "Big Stick" policies that presume that the US has the right to dominate the Americas and make other countries dance to our tune. It's time we stopped shitting on our neighbors once and for all. 

For the record, anytime I mention a wrong by one I am never intending to justify the wrong of another. 

I agree with you that the US Pesident publicly ordering the kidnapping of another country's leader is novel. Closest comparisons I can think of off the top of my head are cia sponsored coup d'etas such as Guatemala and Iran in the 50's

Admittedly my list didn't fit your exact scenario but it did (I think) provide general examples of the unconstitutional military actions for which we both share a growing disdain. 

Thank you for clarifying your intended meaning of the word invasion. I usually use the word as you did. I also recognize a more general/colloquial definition of the term to include airstrikes and bombings. I would wager that if another country bombed my neighborhood I wouldn't need to see any soldiers before I felt invaded. 

The discussion was lack of constitutionality.

Well, yeah, but when deciding/ruling on the legality of an action, strict definitions are needed. Just like Trump's definitions of "emergency" and "insurrection" to try to justify his, um, invasion of American cities.

One of the many weaknesses of the Founding Fathers' creation was to fail to define such critical terms, under the false assumption that everyone would agree on said definitions. Of course, they made other blunders, such as codifying and endorsing slavery, the Electoral College, lifetime SCOTUS appointments, and not realizing how easy it would be for one party to seize absolute power and blot out democracy, as is happening now. They also couldn't fathom the concept of a completely evil, self-serving, irresponsible President who would routinely violate the Constitution, despite his oath.

China, a country that wants World domination, wants control of Venezualsa.  Either we stop this or we don't stop this.   BTY, I learned some interesting information after the attack that you didin't.
