I am sorry I am asking [about the "way English native speakers speak",][1] many times.

And let me apologize in advance.

Granted, however, I would like to ask, as it is in the title

Can we say we can call it the English grammar when the speaker drops the articles because of the difficulties of the pronunciation??????

For example, please listen to the link's speech.

The U.S ambasssador Samantha says at from 2:35 ～

"I think that China is genuinely worried about the threat, Kim Jung Un, and his
nuclear programms poses to the penninsula and to **international peace security**....."

Now, I am assuming due to the difficulties of the pronunciation, the definite article "the" was "intentionally ( or unconciously )" dropped. I think this is very strange because she is using the definite article "the" before the word pennnisula but not before "international peace security". ' which is singular )

Can I conside this kind of "habits" or "tendencies", which I find many times when I listen to something, as the "correct" or "standard" English grammar?

I guess it is happening without being paid due attention by the native speakers 
( even by the U.S ambassador! ).

Thank you for your any kind of answers or comments in advance.
