You really haven't read this thing, you Nazi piece of shit.
And if that isn't enough for you?
Are you even American?
Perhaps you forgot this:
The 10th Amendment:
"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
And, how does the rest of that not fall under "ensuring domestic tranquility?" Maybe you should pull out your dictionary and look up the words "domestic" and "tranquility."
Domestic - existing or occurring inside a particular country; not foreign or international.
Tranquility - the quality or state of being tranquil; calm
The first four you listed are essential to the common defense of the citizenry (which also includes securing our borders). How does securing our borders not fall under such clauses?
1. Responsible for Laws (Justice).
2. Insuring Domestic Tranquility.
3. Provide for the common Defense.
4. Promote the General Welfare.
1. Responsible for Laws (including but not limited to passing laws related to Immigration Control and Enforcement and that existing laws are properly enforced).
2. Insuring Domestic Tranquility (including but not limited to insuring all laws pertaining to illegal immigration are enforced, and keeping illegal immigrants from disturbing the peace in any given area of the United States).
3. Provide for the common defense (including but not limited to ensuring that illegal aliens do not actively try to cross our borders illegally, engage in any criminal activity if they have entered illegally, and charge them for any crimes committed while in the country illegally).
4. Promote the General Welfare (including but not limited to passing laws, statutes, and appropriating adequate funding to the proper Immigration and Naturalization agencies to ensure the enforcement and implementation of the previous three clauses).
