I just can't believe what my government is threatening to do and may actually do before these words appear in print----bomb a sovereign country. As Tom Benn, a well-known member of the British Parliament, said last October in a letter to his foreign his secretary, Robin Cook: Air strikes against Serbia would constitute a total breach of international law, of the Charter of the United Nations and of Article l of the NATO Treaty, which commits NATO to upholding the U. N.

We are threatening to bomb the Serb's not because they have invaded a foreign country but because they refuse to accept an agreement, which we have crafted, to resolve a domestic conflict inside Yugoslavia and to permit the entrance of NATO troops to enforce it.

What or who gives us the authority to do such a thing? Some say the United Nations. But the United Nations and the League of Nations before it were created specifically to prevent a nation, or combination of nations, from infringing on: an independent country's sovereignty . We are arrogating to ourselves the power to judge a country for seeking to put down terrorism within its borders as well as to protect its borders with foreign countries.

More serious in the long run will be the precedent we would be creating. Our proposed actions would provide the arguments to justify a power or a combination of powers to invade some country in search of justice for a minority or minorities. This could be some Arab states, perhaps in agreement with Russia, or it could be China seeking to take over Taiwan. And what if the Hispanics in Texas or California should desire to detach a part of those states, appealing, for foreign intervention to come to their assistance.

In any one of the hypothetical situations, power would be decisive. We will have provided the legal justification. Do we really to do that?

I am disturbed not only by what my government is about to do but also by the apparent bankruptcy of the political opposition. The Republicans have yet to craft a credible foreign policy programs for the United States. ALEX N. DRAGNICH, Bowie
