To answer your question (which, yes, I'm sure was rhetorical)...
They've already gone well beyond that point.
...and it will only get worse.
The definition of "infringe" was more succinct when the Constitution was written.
From
Johnson's Dictionary of the English Language: 1755:
To INFRINGE.
v. a.
1. To Violate; to break laws or contracts.
2.To Destroy; to hinder.
Note that the latter definition - to destroy or to hinder - wasn't obsolete back then.
Johnson gave a rather pertinent example of the first definition in his dictionary:
"Those many had not dar'd(dared) to do that evil,
If the first man that did th'(the) edict infringe,
Had answer'd for his deed." {From Shakespeare, Measure for Measure}
Had the first Congress or state legislature suffered from the first law infringing upon the Right to Keep and Bear Arms, we'd not be having these discussions, we'd be freely armed and carrying wherever we went no matter how we got there.
As for this treaty, no treaty can be made that would infringe upon our Right to Keep and Bear Arms. Only treaties made, or that shall be made, under the authority of the United States have the force of law(Article VI, Clause 2). The United States is prohibited to infringe upon our Right to Keep and Bear Arms by the Second Amendment, therefore, has no authority to enter into any treaty that would infringe that right.
